While working with Skype, it is not uncommon for a message to appear that the connection cannot be established. Appearing at the wrong moment, the message breaks the connection, preventing the conversation from finishing. Getting Skype back to work is easy. You need to understand the causes of the problem and perform a sequence of actions.

Reasons for the error

After entering the login and password, these data are sent to the server for verification. After confirming the data, the server informs the program on the computer that the data is valid and authentication has been completed. If a connection error occurs, it means that the program cannot synchronize with the server and does not allow the user to access the network.

Among the reasons for the lack of connection, there are the following:

1. The version is outdated and out of date.
2. The program is being blocked by the Windows firewall.
3. The computer is not connected to the network.
4. The provider has blocked the work of Skype.
5. The application server is not responding.
6. The program has crashed.

I will analyze the cases in which a malfunction occurs in Skype.

Internet connection check

The first thing to do if Skype failed to establish a connection is to check your network connections. Launch any browser and try to visit any site. In the absence of the Internet, we see a corresponding message.

Checking the program version

Microsoft regularly releases updates for their product. The company is interested in ensuring that users use only new versions of the product. Therefore, older versions are unstable and often fail. Information about the relevance of the version is available in the "Help" section. In the pop-up window, click "About Skype".

In addition to the version, the manufacturer indicates the year the update was released. Versions released last year are considered out of date.

The update is made through the official website. We go to Skype.com and click "Download".

Disabling the firewall

Another reason why Skype writes "Could not establish a connection" - windows lock. Firewall is a standard protection that is present in all Windows versions. It blocks suspicious activity from the network. Firewall - useful application, but his work also affects the stability useful programs and applications. In particular, it can cause crashes in Skype. To check the effect of the firewall on the software, you need to temporarily disable it:

1. You can do this through the "Control Panel" by selecting "System and Security".
   
2. In the new window, select "Windows Firewall".
   
3. And then Turn the firewall on or off.
   
4. Disable protection, and save the settings by pressing the "OK" key.
   
5. After that, restart the program. If the problem is not solved, its roots are probably in the work of the antivirus.

Disable antivirus

The antivirus has a list of programs that it blocks, or prohibits access to the Internet through them. Skype sometimes falls into their number. If this happens, add the program to the antivirus exclusion list, and network access will be restored.

Router settings

Skype crashes are caused by a malfunctioning router. To eliminate this possibility, do the following:

1. Open your router settings. To do this, write in the address bar of the browser (for example, Google Chrome) 192.168.0.1 (or 192.168.1.1).
   
2. Go to "Virtual Servers".
   
3. In the "Description" field, enter the name of the program, enter 4960 in the "Port" field, specify the standard IP for the network, with a difference in the last cell (for example, 192.168.1.85) and click "Add".

Often, users are disturbed by notifications about the inability to establish a connection in Skype. This error appears if, when trying to authorize, the messenger could not “reach out” to the server, or simply did not receive a response from it.

In such a situation, he has no choice but to postpone the Skype login process until better times. Why and what to do? You ask.

Here are some reasons for this application behavior:

1. Perhaps you are using an outdated version of the messenger.
2. The application is blocked by the firewall.
3. You are not connected to the World Wide Web "Internet", or its settings are not correct.
4. Your Internet Service Provider (ISP) or the administrator of the network you're on may have blocked access to Skype.
5. Critical violation of the messenger itself.
6. For some reason, the application server may not work, for example, technical work.

We will delve into the essence of each problem and look for reliable solutions.

• The most common cause of an authorization error lies in the use of an outdated version of the program. There is only one way to deal with it - upgrade the old one or reinstall new version applications, preferably a recent release.
• The second most popular problem of the inability to establish a connection is incorrect adjustment of the settings Internet Explorer. For the operating system, this browser is the main one, so changing its settings affects the operation of another software Skype is no exception. To correct the situation, reset your browser settings to the original ones.

• In the case when the first two scenarios are not suitable, you should think about the issue of limited access to Skype domain servers. To check this, use a special test program. If the test results are disappointing, turn off the firewall, or if you advanced user, remove the restrictions in it. Re-test. If this time you are denied access, you should contact your Internet service provider for help and clarification.
• The error may also lie on the application server itself due to some technical work. Checking this is easy - you just need to go to one of the many services on the Internet and see if the Skype server is available. If the domain servers are in good condition, then the error occurs on your computer or gadget. Otherwise, you need to wait until the server is up again, often it does not take much time.
• Sometimes the culprits for denied access are corrupted files the application itself. In this case, restarting the program will help. If the error persists, you will have to send the files "%appdata%\Skype\shared.lck" and "%appdata%\Skype\shared.xml" to the trash.

What to do in this case? Why can this happen at all? Answering these questions is not so easy. Especially when you consider that the application crashes most often on computers. Nevertheless, today we will learn how to deal with the problem under study. So what should you pay attention to first?

Internet connection

Skype failed to connect? What to do? The first thing to do is to check for a network connection. Its absence results in the mentioned message.

In general, this alert indicates that Skype cannot connect to the application server. The program gives a signal, but does not reach the server. Accordingly, the application cannot work.

To check, you can open a browser and try to go to any site. Did not work out? So something is wrong with the internet! This is what caused the crash.

Skype Internet connection problems can be caused by:

• arrears in paying for access to the network;
• failure at the provider;
• accidents and technical work on transmission lines;
• OS crashes.

You can try to restart the Internet and the modem. As soon as network access is restored, an error like "Skype cannot establish a connection" will not appear.

Old versions

The next scenario is that the user has an outdated version of Skype. Such applications eventually cease to be supported by developers.

Did you get the message "Skype could not connect"? What to do? It's time to check the software version and update it if necessary.

To do this, you will need:

1. Open the Skype authorization window.
2. Go to "Help" - "About Skype".
3. Look at the version of the application and the year the assembly was created.
4. If necessary, open skype.com and download from there latest version applications.
5. Install Skype and try to connect again.

Important: old version It's better to remove the software. To do this, it is recommended to open "Start" - "Control Panel" - "Add or Remove Programs" - "Uninstall ...".

Firewall

But this is not all the options for the development of events. Skype does not have an Internet connection sometimes due to the built-in firewall. It appeared in Windows with the version "Windows 7". To correct the situation and enter Skype, the mentioned service will have to be disabled.

This will require:

1. Go to "Control Panel". The corresponding item is located in the start menu on the left side of the screen.
2. In the "View" section, set the "Category".
3. Select "System and Security".
4. Click on "Windows Firewall".
5. In the left menu, click on "Turn the firewall on or off".
6. Set "Disable" everywhere.
7. Click on "Save/Ok".

Now you can try to start Skype again. If it's a firewall, then the application will start to work in full force. Still a notification appears on the screen What to do next?

Antivirus

It is possible that the application interferes with the work installed antivirus. No wonder the developers recommend turning off this software when initializing programs and when starting some utilities. Maybe the Skype files are recognized as malicious for one reason or another.

How exactly to disable the antivirus? It all depends on which PC security application a person has installed. Most often, it is enough to right-click on the software icon in the Windows tray and select "Exit" there.

Equipment

Sometimes it is not possible to establish a connection in Skype due to the modem/router. For example, if it fails or a reset occurs. Unfortunately, users forget about this point.

More precisely, the following guidelines will help:

1. Type 192.168.0.1 in the browser. The number may change. It can be clarified according to the documents of the router.
2. Get authorized in the system. Usually the default password and login is admin.
3. Go to "Virtual Servers".
4. Click on the "Add" button.
5. In the "Name" section, write Skype, in the "Port" (final) - 4960, for example.
6. Click on "Save".
7. Open Skype.
8. Go to "Tools" - "Connection problems ...".
9. Specify the port specified in the router settings in the "Use port" window.
10. Click on "Save".

Reset Skype settings

Skype failed to connect? What to do in this case? Last tip is resetting the application settings.

How to bring the idea to life? Have to:

1. Open Start.
2. IN search string type %appdata%.
3. Enter the mentioned folder.
4. Open the Skype section.
5. Select all documents and delete them.
6. Launch Skype and log in with your username.

All of these methods are found to be quite effective in practice. But they shouldn't stop there.

Extreme measures

Skype not connected to the internet? All the proposed methods did not get rid of the problems? Under such circumstances, you can act differently.

How exactly? You should try:

1. Implement complete reinstallation programs.
2. rollback operating system for a time when Skype was working fine.
3. Check your computer for viruses, remove a computer infection and enter the messenger.

The most radical way is considered to be a complete reinstallation of the OS with formatting hard disk. Fortunately, this technique is rarely needed. Unable to connect in Skype? From now on, it is clear how to act in case of such an error. She's not as dangerous as she looks. The main thing is to understand why the failure occurred. This is not always easy to do!

Increasingly denser Internet enters our lives not only as computer network for the transmission of various information, but also as a means of voice and video communication. To contact via global network different clients, programs are used. And one of the most popular applications today is Skype.

Thanks to which you can hear the interlocutor, transmitting an audio signal, as well as video through thousands of kilometers in a matter of seconds. But sometimes there are some technical problems interfering with the normal operation of the program. Their search and solution is not always an easy task.

The main reasons for the lack of communication

The client in question is a fairly reliable application, but communication can often be lost. What to do in such a situation?

It is necessary to check the most important reasons due to which there is no connection:

1. no internet connection;
2. too low throughput networks;
3. incorrect application settings;
4. there are problems in the hardware of the computer;
5. an outdated version is used;
6. "supernodes" are overloaded.

Photo: Failed to connect

Most often there is no connection in the case when there is no Internet connection. Since all the work of the client in question is based precisely on interaction with other computers through the global web.

Also, the connection may be absent due to too low speed of the communication line. The problem can be both hardware and software. Or the tariff at which communication services are provided does not imply the presence of sufficient speed for comfortable communication on the network.

If the Internet is available, but it still fails to reach the required subscriber, perhaps the reason lies in the incorrect setting of the communication program. The communication port may be incorrect or something similar.

Normal communication is also not possible if there is a problem with the computer hardware. For example, if the video camera or microphone is broken. Or the drivers are simply installed incorrectly.

More early versions are not always compatible with later ones. There may be some conflicts at the software level.

Another problem when establishing a connection with another subscriber can be the congestion of “supernods” - these are kind of directories, the client accesses them when dialing. If there is too much at the same time a large number of calls to one such node, then the connection may be absent.

Video: How to fix the error

We find solutions

Let's figure out how to fix the problems that arise with a minimum investment of time. It all depends on the cause of the failure.

If there is no connection due to the lack of an Internet connection, then to solve this problem, you simply need to connect to a working communication channel.

The same solution can be applied if the speed is too low - it may be necessary to change tariff plan service from your provider. Disabling such a function as image transfer can improve the situation - the video "weighs" quite a lot.

For those who cannot start the client due to errors 1103, 1101 and 1102, the first thing to do is to understand the cause of their occurrence. They mean that your client cannot connect to the server.

If the Internet is working, then the problem most likely lies in the firewall, or the proxy server used.

The solution lies on the surface, it is necessary to allow the client in the firewall:

1. use ports from the range 1-65535;
2. when the first step is impossible to implement, you should open port number 443. Only version 0.97 and older can work with it;
3. if the first two points are missing for some reason, then you can open a connection through port 80.

You can select the port for working in the application in the “Settings”-> “connection” section.

If the application still continues to display a message that the port is unavailable, you need to update the program or install it again.

Program update

Updating the client in question for communication is very simple:

1. to update the existing version, you must click the "Download" button;
2. when the download is finished, you need to click on the "update" button.

Customization possible automatic update programs:

Enabling this feature allows you to update the communication client automatically.

Turning off the firewall

When you sign in or when you try to dial out to the interlocutor, you may experience problems due to an incorrectly configured firewall.

Turning it off will fix it, you can do it as follows:

If, after this operation, any data transmission errors occur, then they will not be associated with the firewall.

Skype in firewall exception

Quite often it happens that a message appears from skype "we could not establish a connection with the download server". This may indicate a conflict with the firewall. For normal operation of the client, it is not necessary to disable the protection system, just add the application to the exceptions.

This is done as follows:

Why can't connect

It happens that Skype does not start, or it was not possible to establish a connection using it. The solution to this problem is often simply uninstalling the application and then installing a more recent version. And old program must be removed completely, preferably with the help of some special "gadget" - CCleaner or other.

Also, establishing a connection to the server may fail due to the closing of the required ports by a working firewall or firewall.

There are two ways out of this situation:

• add to exclusion list;
• allow the required ports to be used.

Checking the settings

The key to the normal operation of the program in question is the correct setting. First of all, sound and video.

Sound settings can be done both in the program itself and through the control panel.

The last way is more acceptable:

• open the "control panel";
• find the section "sounds and audio devices";
• in the section that opens, you can easily edit the sound or microphone level.

Video setup is as follows:

Checking the router settings

Often one of the reasons for the inoperability of the client in question is closed ports on the router. You can edit this parameter using the Web interface, each router has its own.

After entering the login and password that provide access rights for editing settings, you need to visit the Advanced Port Forwarding Rules page. This window will allow you to see which programs use which ports. And assign the desired one (port 80 or 443).

Fixing bugs

Most cannot enter the program - the client due to various errors, correcting which, you can achieve normalization of work.

The two most common types of errors are:

• databases are corrupted;
• launch of the second copy of the program is not possible.

In the first case, the best way out of the situation is to reinstall.

The second case is simpler, the following measures can be applied to eliminate the error:

Most often, these troubleshooting methods help you get your application up and running.

The considered client for communication via the Internet has many advantages, its work is quite stable. Even if there are any problems when creating a connection or setting up, they can most often be resolved fairly quickly and without difficulty. This is the reason for the great popularity of this service.
