A message that appears on the computer screen that the proxy server refuses to accept connections means permanent or temporary interruption of access to the Internet through the browser.

The causes of the problem can be different, however, regardless of them, the issue should be resolved as quickly as possible.

As a rule, access is not restored without user intervention - and in order not to call the wizard (and, therefore, to save time and money), it is worth taking a few simple steps.

Causes of the problem

In most cases, the browser accesses the Internet using a wired or wireless connection provided automatically. The user does not need to make any effort to do this - just set up the connection and use the network once.

However, if the proxy server settings go wrong, instant access to the network becomes impossible. For an inexperienced user, such a problem may seem insoluble - and, nevertheless, there are ways to fix the error.

The reason for the message about the inability to connect may be:

• a key combination accidentally pressed by the user while working in the network;
• settings that are lost due to a sudden shutdown of the computer (power outage, burnout of one or more parts, improper shutdown of the computer);
• the effect of a virus on the system or the consequences of an incompletely removed malicious code.

It is worth noting that if a problem with the proxy server appears, the Internet may work. So, for example, the torrent client will continue to download files, Skype and even client (not browser) games will continue to work. However, you will not be able to access the network using a browser - neither load the page, nor watch a video, nor work with documents online. When you try to do this, an inscription in Russian or English will continue to appear on the screen.

Rice. 1. An inscription indicating problems with the network connection.

Setting up a proxy server is practically independent of the platform variant when it comes to Windows. Moreover, the problem often lies not in the operating system, but in the browser.

What shouldn't you do?

If there is a problem with the lack of connection, the cause of which is the lost proxy server settings, you should neither panic nor contact Computer service... In most cases, you can solve the issue on your own, saving money on repairs and the time it will take. It is also not necessary to reinstall operating system, and even the browser in which the connection refused message appeared.

Knowing the ways that you can deal with the problem, you will have to spend from 5 minutes to half an hour to restore access to the network, depending on the number of options tested. As a last resort, the proxy server is turned off altogether. Although this option significantly reduces the security of the connection.

Priority user actions

The first action when a proxy server accepts a connection error message appears should be to clear the browser cache. To do this, select the appropriate item in the browser settings, and clear the entire history - cookies, page visits and cached files. In the Opera browser, you can clean it using the "Security" item.

Rice. 2. Clearing cookies in the Opera browser.

For the browser Mozilla Firefox the same actions are performed on the "Privacy" tab. The cleaning principles in other browsers are roughly the same. Moreover, when deleting cookies, one should not forget about the history, which is sometimes cleared separately. And as a preventive measure, the user can turn off the saving of cookies and history - this will simplify the work with the network, although it may lead to slower access to certain resources.

Rice. 3. Clearing the cache in the Mozilla browser.

Browser customization

Clearing history and cookies can be called the preliminary stage of restoring network access. As a rule, it will not be possible to reconnect after that. However, after deleting the excess data, you can do the actual proxy setup. To do this, the user of the Mozilla browser needs:

1. Go to tab additional settings;
2. Open the "Network" section;
3. Click on the network settings button;
4. Disable automatic proxy settings and fill in all forms manually.

Rice. 4. Manual setting proxy settings.

Further actions of the user depend on the type of protocols used by the system. So, with the support of only two main options, HTTP and SSL, you should enter the addresses and ports in the appropriate fields (you can find them using the control panel or the 2ip.ru website). In this case, the "SOCKS Node" parameter remains empty.

If, on the contrary, only the Socks protocol is supported, the configuration requires filling in only this field. The addresses and ports for SSL, FTP and HTTP should be left blank. The result of these actions, as a rule, is the restoration of access through the proxy server.

If it was not possible to find out the addresses and ports for the protocols used, or the setting did not help to connect to the network, it is advisable to set the use of system data or their automatic detection. Then go to last ways fixes an error with a proxy server - using antivirus and cleaning the registry.

Correcting the error using antivirus

One of the most common causes of the error is a virus that got onto the computer from the network or when connected to a third-party storage medium (USB flash drive, external hard disk).

Malicious code may block the Internet connection through the browser and prevent you from using other applications for this. The solution to the issue is to find and remove the virus, for which it is advisable to use an antivirus. Moreover, not the one that is already installed in the system (after all, it has already proven its inefficiency), but a new one.

For this, for example, the "one-time" anti-virus Dr.Web Curelt is suitable, which can fully scan hard drives, registry and operating system. Its advantages include almost 100% virus removal guarantee and free use. The disadvantages include the need to download it again or update the databases each time, as well as slow work- scanning can take several hours.

Rice. 5. Window of the anti-virus Dr.Web Curelt.

After checking the system for viruses, you should restart the browser (and best of all, the entire system) and check the network connection again. If the proxy server is working properly, network access will be restored.

So, viruses were the cause of the problem. It is desirable for the user to change already installed antivirus and attitude towards protecting your computer. That is, check the system more often, do not go to sites with suspicious content (to determine them, you can install an antivirus program directly in your browser).

Cleaning the registry

The last way to solve the problem with the proxy server is to clean the registry. You can call the editor to make changes using the Regedit command in the Run menu (Win + R). The path to the item to be changed can be seen in the figure.

Rice. 7. The path to the registry key that you want to check to restore the proxy server.

This section requires:

1. Find the Appinit_DLLs file (for Windows 10 - AutoAdminLogan);
2. Erase all data that is in it (the file must remain empty);
3. Close the registry editor;
4. To restart a computer.

If the file is already empty, no action is required with the registry. Unnecessary changes in the editor can lead to even more serious problems in the computer than the lack of a network connection.

Disable proxy server

In cases where attempts to fix the problem did not lead to positive outcome, you can try to completely disable the proxy server. To do this, open a browser window, find the connection parameters and turn off the proxy server. In Mozilla Firefox, this can be done in the Advanced Settings tab in the Network menu.

Outcomes

After all the options for solving the problem have been tried, access to the Internet through a browser appears in almost 100% of cases. If this does not happen, most likely you will have to contact a service specialist. Or try to reinstall the operating system yourself, first saving valuable information on non-system partitions of the disk.

Can't connect to proxy server

About what to do if the browser Google chrome, Yandex or Opera writes that it cannot connect to the proxy server when opening the site.

Today there are quite a lot of users of modern computer systems Windows-based who are familiar with the concept of a proxy server, or at least have heard of it. Let's see what it is and why there are situations when the proxy server does not respond.

What is a proxy server?

In simple terms, a proxy server is a specialized service that allows you to connect to the Internet or a local network through the so-called indirect (indirect) requests.

In other words, the proxy server acts as a kind of intermediary between the user of the computer terminal and the requested resource. As it is already clear, it is not at all necessary that it be on the World Wide Web. But very often you can find the appearance of problems associated with the fact that the proxy server is not responding. Now we will look at the most common situations and methods for eliminating them.

Causes of problems

As a rule, the proxy server does not respond mainly when using incorrect settings. It would seem that the addresses were entered correctly, but at one point the connection stops working. Why?

This is often due to incorrect or forced termination Windows work, say, in the event of a sudden power outage (in cases where there is no block uninterruptible power supply), disabling some system services and applications when the "operating system" hangs, etc. In such moments, the proxy settings simply have the property to "fly off". But you can fight this, and even very successfully.

In some cases, the problem that the proxy is not responding may be due to its own health. This can be temporary maintenance, software component updates, and more. And we are not talking about the fact that if the provider service does not provide services for connecting using a proxy, then adjusting its parameters is, in general, absolutely pointless.

The proxy server is not responding. What to do?

First, let's look at the basic proxy settings that are called in additional parameters properties of the default Internet browser. For standard Internet Explorer or Edge (Windows 10), such settings are configured through the standard Control Panel.

We will assume that the provider still uses a proxy. If the proxy server does not respond, Windows 7, for example, or any other modification simply does not recognize its actual address when trying to establish an intermediate connection.

What to do in this case? Yes, just enter the correct values ​​of the addresses provided by the provider when the terminal is connected to local network or the Internet.

Local networks are worth mentioning separately. The fact is that failures, even when the proxy server does not respond, Windows 8 can also interpret in its own way. This, by the way, applies to almost all of the latter Windows versions starting with XP. Pay attention to whether the proxy setting is enabled for local addresses. If there is a checkmark next to this item, it is strongly recommended to remove it. Quite often, the problem arises precisely because of this, since the system does not refer to the address of the proxy server itself, but to the identifier of another machine connected to the local network. Although such addresses, in theory, have nothing in common, nevertheless the Windows operating system of all versions is not protected from such failures.

Using anonymous proxy servers

With anonymous resources on the Internet, which are proxy servers that allow you to change or hide the real external IP address of a user's computer when surfing the Web, the situation is somewhat different.

Here, basically, connection errors arise precisely because of the problems of the resources themselves. This often manifests itself in the fact that the browser displays a message that the gateway timeout has expired). It only means that the requested resource, which can work either as a proxy server or as a gateway, did not receive a response in time from a server located in the hierarchy of connections above it.

Here you can do it in the simplest way - just as a last resort (if you are sure that the resource is working), just restart the system. Perhaps, sometimes it may require disabling the antivirus or firewall or adding the site itself to the list of exceptions, because the antivirus, or the firewall, are capable of blocking some, in their opinion, suspicious sites.

Conclusion

In principle, we have considered the most common situations and the simplest methods of correcting them, just without going into the technical side of the issue. Separately, it should be said that in most cases the lack of communication with proxy servers is not associated with any critical disruptions in the operation of operating systems. Rather, it is a special case.

The whole point is not even in user settings, but in the performance of the resources of this type themselves, especially in the case of using anonymizers. Actually, as can be seen from the above material, the problems can be solved quite simply. Sometimes you even just need to check if the network connection and access to the Internet, otherwise it also happens that the icon in the system tray shows that the connection is active, but in fact it is limited or absent altogether (most often in relation to connections based on Wi-Fi connections).

Nowadays, users often come across who, at the next attempt to open Internet pages, find the message: "Unable to connect to the proxy server." Of course, such a message causes some shock, since ignorance of the computer does not allow you to quickly solve the problem.

There is a way out of any situation that can be done by any user, so you should not rush to the nearest workshop or call a specialist at home. However, it is also undesirable to stay idle, since a proxy is a special channel that passes all client traffic through itself. Fraudsters often use this by stealing personal data (password, login) from social networks and electronic wallets. When such a proxy is covered up, the ill-fated inscription appears on the screen: "Unable to connect to the proxy server."

When a proxy connection error occurs, you should first check the Internet connection itself. If the pages do not load in browsers, but Skype and torrents are working absolutely normally, therefore, there is a problem on the computer that needs the user's participation.

Change settings

To return automatic connection PC to the network, it is necessary to make some adjustments to the properties of browsers, which is not difficult.

In cases where Google Chrome is used, you should enter its basic settings, and then proceed to adjusting additional settings, finding the "Change proxy server settings" option in the "Network" group. By clicking on the selected parameter, a new window with several tabs will appear, among them it is necessary to identify "Connections", and then go to it. Then, at the bottom of the new window that appears on the screen, the "Network Settings" parameter will be located, you should also click on it. Now another new window will open, where a bird will be installed opposite the phrase "Use a proxy server for local connections". Just this bird should be removed, and put it at the top, opposite the phrase "Automatic determination of parameters". It remains now to agree with the changes made by clicking "OK" each time the windows are closed.

When using other browsers, such as Yandex or Opera, all changes are made in a similar way.

To make changes when using other browsers, adjustments are made through Windows capabilities... The change scheme is only partially different from the one described above. Initially, you should enter the "Control Panel", then go to "Internet Options", and then the adjustment process will be completely identical to the previous recommendations.

It should be noted that it is not recommended to make any changes on your own at the workplace, since often in organizations, access to the Internet is accompanied precisely through the server. By making changes to the parameters yourself, you can completely block the Internet access. For this reason, if the message "The proxy server is refusing connections" appears on the work computer, it is best to contact system administrator, in whose functional duties the elimination of all network problems is spelled out.

If the proxy server still does not respond on the home PC, and the user absolutely knows for sure that the Internet is accessed through the server (this happens when connecting to a small local network), then the address and port of the proxy server should be checked. If necessary, enter the correct data manually. Unfortunately, if the correct address and port are identified, the only option is to check the PC for viruses, otherwise you will have to contact the service for targeted help. technical support or to the network administrator.

Connection failure due to malware or registry errors

The proxy server also refuses to accept connections when the PC is infected with malware. By the way, if, after making changes to the Internet connection parameters in the above way, it is possible to restore the browsers to work, but after restarting the system, the problem reappears, then this indicates that the PC still picked up dangerous viruses... Therefore, the user is simply obliged to direct all efforts to combat them.

Virus removal

You can only remove viruses that negatively affect your network connection settings using antivirus software.

The simplest is AVZ, although you can also use other antivirus programs if you want. The main requirement is that their databases are updated to the latest version.

When using AVZ, you need to click on the item in the "File" menu, then select "Restore system settings", in the window that opens, check the boxes next to each parameter, except for two:

• "Cleaning up Hosts files".
• Completely re-creating SPI settings (dangerous).

All that remains is to reopen the browser and check if the problem is resolved.

Cleaning the registry

An Internet connection error, accompanied by a message about a malfunctioning proxy server, can occur for various reasons, but one of the additional ways to successfully fix it is to clean the registry.

Initially, you should go to the registry, and for this you need to enter or pre-copy and then paste the following entry in the OS window: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ WindowsNT \ CurrentVersion \ Windows \

After that, a dialog box appears on the screen, on the left side of which there is a list of folders, and on right side- list of attached files. It is important to check the folder or file named "Appinit_DLLs", for Windows 10 - "AutoAdminLogan". These folders must be empty. If there is something there, then all content is deleted without regret.

So, having found problems with the Internet connection, in which the system reports that the proxy server is to blame for everything, you should not hastily reinstall the browsers used, and even more so reinstall the operating system. It is enough to read the recommendations experienced users, do all the steps, and the error will be eliminated. Otherwise, you still have to take your PC to the workshop, as this may indicate a technical failure.

"Proxy server not responding" - this error occurs for most "users" when trying to access various portals in the browser.

The error is quite simple to fix, the main thing is to understand the reasons and choose the right way to solve the problem.

In many situations, Internet access is provided automatically. The "user" needs to correctly configure the connection once, and then nothing will have to be configured. However, there are times when an error appears on the monitor indicating the impossibility of connecting: "The server is not responding."

There are several reasons for a proxy failure:

1. Invalid address (IP or domain) specified.
2. Anti-Virus blocks an outgoing request to this address.
3. The presence of viruses or the result of an incompletely destroyed malicious code.

Please note that the work with the Internet will be preserved. The user will be able to download files via torrent, play client games. However, access to the network through a browser and work with files online will be suspended. When you try to access the network, an error appears on the screen in Russian, or English indicating that the proxy cannot respond.

First steps

First of all, you should understand that the reason why the proxy is not responding does not depend on the choice of OS. Most often the case is related to the browser.

The first step you need to take is to clear the cache of Opera, Chrome, Mozilla and other programs. To do this, you need to go to the "Settings" and select the appropriate items. Let's look at the steps for each browser separately.

Ready. Each of these methods allows you to fix the error connecting to the proxy server if it is not responding. If these steps did not help, then you should change the browser settings.

Browser settings

After clearing your browser history, the next step is to determine the correct browser settings. Let's look at the actions using an example Mozilla browser, necessary:

The following steps are protocol dependent. If the user uses HTTP and SSL, it is recommended to fill in only the appropriate fields, leaving the SOCKS Host section free.

If the "user" uses the Socks protocol, this field must be specified.
You do not need to fill out the information for SSL, FTP, and HTTP. We leave it unchanged.

In the case when these manipulations did not help, and the proxy does not respond, you need to scan your PC for viruses.

Getting rid of viruses

So, all the manipulations that are indicated above have been carried out, and the problem with the proxy server still "pops up". Then you need to check your computer for malicious codes. In this case, it is recommended to perform the analysis with a new antivirus program, since the old one does not do her job in full, since she could not find the reasons why the Internet is not responding. You can try to download free antivirus or use the trial period for paid programs.

If a virus is detected, it must be “cured” or removed completely. After these manipulations, it is recommended to reconnect, if you cannot connect to the proxy server, you need to proceed to cleaning the registry.

Cleaning the registry

If you cannot connect to the proxy server and the internet is not responding, cleaning the registry is one of the most complicated and confusing processes. But with strict adherence to these recommendations, the actions will not seem like that:

Other changes in the registry are not required to avoid more serious problems in the functioning of the PC. But if in this case the connection is not possible and the Internet is not responding, you need to deactivate the proxy server.

Disable proxy server

The above manipulations should help resolve the pop-up error: "Failed to find proxy settings." If these steps did not help to solve the problem and the proxy does not respond, the user is advised to try to deactivate the proxy server. Let's apply the sequential steps for the example of the Mozilla Firefox browser:

Similar manipulations can be performed with the Opera browser:

There is also additional features... Opera has a Proxy-server option, it is located in the "General" section, the "System" item. Go to the Proxy parameters and do all the necessary manipulations.

Although the security of the network will be reduced, the connection will be restored and the error for which the proxy was not responding will be eliminated.

Conclusion

If you can't connect to the proxy server and the internet isn't responding, that shouldn't scare users. Eliminating the error does not take much time and does not require any complicated and confusing manipulations. And with our support, difficulties will not arise at all.

A proxy server is a service that is hosted on a local PC or a remote host. This tool performs the following functions: filters traffic and ensures its safety, guarantees anonymity when visiting sites, increases the speed of information transfer, and much more. Sometimes a system that connects to the network through a proxy,. In this article, we will analyze why in such situations the message “Check proxy server and firewall settings” appears and what the user needs to do to fix the error.

Settings check message

Finding a solution to the problem “Check the proxy server and firewall settings” depends on whether the user connects to the network through a proxy or not. By functional features staging servers can be divided into two types: web servers and applications installed on the PC. If the connection is made through an application (Kerio or Squid), then you need to check if the settings are not lost. In the case of access to the network using remote proxy resources, there are two options for solving the problem:

• view the list of available intermediary servers;
• make sure the proxy port is in this moment is not busy with another task, as a result of which the service is temporarily blocked.

To make sure that the PC is working normally, access the network through a proxy from another computer. If the “Check proxy and firewall settings” message also appears, then take the following steps.

Similar errors:

Step 1. Disable the proxy server

First of all, you can try to disable the proxy server, although this will be quite painful for the user. The method is called painful because access to the network will remain and sites will be loaded, but not all resources can be accessed, but only those that do not work through an intermediate server. The rest will remain blocked. You can disable the proxy in the settings of the browser that you use to access the Internet. Of course, the settings menu looks different in each browser, but in general terms, the process can be described as follows:

Proxy data

Step 2. Configuring the broker

The more effective method is to configure the proxy server. Consider this process... Lists of free intermediary servers available for a specific country are posted on the network. What do you need to do?

Entering IP addresses and port numbers

• restart the browser (in our case, it is Yandex).

Now you can check your IP address with one of the services. It will determine that you are accessing the network not from your computer, but from the IP changed in the settings. But in this case, there will be no data on the OS and host used, and the information about your location will turn out to be unreliable.

What to do if a proxy server is not used to connect to the network

If you are not using a proxy to connect to the Internet, and the message “Check proxy and firewall settings” still appears, try the following:

• make sure that the Internet is working properly (if necessary, restart the modem / router, or even disconnect them from the power supply for a while);
• reboot the computer as usual - perhaps the system is simply “tired” and needs a short rest;
• open the site from another computer - perhaps there are errors in the operation of the resource or your provider;
• go to the web page from another browser - maybe the browser is not functioning correctly and you need to reconfigure or reinstall it;
• check if the site is not blocked by an antivirus that has identified a security threat (usually the program displays a message about this).

If these steps do not help, try the following. It may be that the developers of the site have changed the IP, and the PC is trying to contact the resource at the old address. In this case, open command line and enter the command ipconfig / flushdns (since the problem may be with the DNS settings).

Entering ipconfig / flushdns into command line

When using embedded software that protects your PC from various threats - firewall, firewalls, firewalls- review the settings, as such programs can block access to blacklisted sites.

Here's what a typical user can do if he encounters the system message “Check proxy and firewall settings”.
