Error in Skype: "Could not connect"

Ошибка в Скайп: «Не удалось установить соединение»

Skype is a free, proprietary, closed-source software that provides text, voice and video over the Internet between computers (IP telephony), optionally using peer-to-peer technology, as well as paid services for calls to mobile and fixed phones. As of the end of 2010, the program had 663 million users. The majority of developers and 44% of general department employees are in Estonia - Tallinn and Tartu.

Often, when the Skype program is launched, users receive a "Connection failed" error that appears during authorization and thus prevents Skype from entering. However, after the developers turned off the old versions from online, the number of users who encountered this error greatly increased.

Ошибка в Скайп: «Не удалось установить соединение»

The biggest problem with this error lies in the fact that the user does not know why Skype issues this message and accordingly does not know how to fix it. By itself, the phrase "Unable to establish a connection" only indicates that Skype can not connect to the server, but does not say what it means, why it happens and most importantly how to fix the error. Well, let's answer these questions and try to solve this problem with the connection.

What does this error mean?

The fact is that when we enter our login and password, Skype sends this data to the official server to verify their authenticity, and the server in turn informs the program if the authorization was successful. So, this error means that Skype does not receive a response from the server and accordingly, refuses to authorize the user.

Why can not Skype connect?

This can happen for various reasons. The most famous among them are:

  • Used the old version of Skype
  • The firewall blocks the Skype program
  • Computer is not connected to the Internet or configured incorrectly
  • An ISP or network administrator has forbidden the use of Skype
  • There was a critical failure in the program
  • Official server is not available

How do I fix a connection error?

Since the reasons for the error can be several, there is no unequivocal advice. That's why I listed below different methods of error elimination:


Typically, the most common error occurs when using the old version of Skype and accordingly, to fix it, you need to install the latest version. You can download the latest version at .


The second popular reason for this is the incorrect setting of the Internet Explorer browser. Since this browser is an important component of the Windows operating system, its incorrect configuration can lead to errors in different programs (as you understood, one of them "failed to establish a connection" in Skype). To fix the error, you need to reset Internet Explorer settings.


Often Skype can not connect to the server if the network administrator, ISP or firewall restricts access to domains. To do this, first try temporarily disabling the firewall and re-open this page - if it fails again, contact your network administrator or ISP for assistance.


Although quite rare, sometimes the Skype server stops working properly. If they work properly, then the error is on your side, and you must eliminate it yourself. And if the servers do not work, you just have to wait a little while the developers do not fix the error.


For other reasons unknown to me, there may also be a "Connection failed" error. I do not know whether the Skype files could be damaged (for example, the database, the configuration file), some OS processes do not work properly, or something else - I only know that to fix the problem, you can trivially restart Skype or even a computer. Sometimes it helps to delete the following files:

  • % appdata% \ Skype \ shared.lck
  • % appdata% \ Skype \ shared.xml
