Sometimes Skype users encounter such a problem that when starting the program, an error appears about there being no connection or the connection goes on forever. And at the same time, the Internet works on the computer, sites open in the browser, and so on.
Causes of the problem
Understanding the cause of this problem when Skype does not connect is extremely difficult. Most often, restarting the computer solves the problem. But in some cases it remains. The issue may be with Skype itself. For example, its data is damaged, or it is being used old version. The failure may also be incorrect setting system, blocking the program by a firewall. Sometimes the essence of the error lies in the operation of the antivirus, which interrupts the connection.
We must also not forget that authentication in Skype occurs with the participation of the browser Internet Explorer. And if its settings are messed up, then various problems may arise.
The result of any of the described reasons is that the program cannot send login information to the server. Then an endless Skype connection occurs or connection errors appear.
Solution
There are 3 simple ways Fixing the crash: reinstalling, deleting Skype files and resetting Internet Explorer settings. One of them will definitely help restore communication.
But before you start trying to fix the problem, you should make sure that the problem is related to your computer. Sometimes, when there is no connection on Skype, it's all about the developer's servers. They can be disabled as a result of a failure or during maintenance work.
Use the resource Down right now. There, information about the servers is presented in the form of a graph. Current state displayed on the right. Up - everything is fine. Down - servers are not working. 
Also try disabling your antivirus and logging in to your account again. It can block communication with servers. In this case, you should add the program to the antivirus exceptions.
Method 1: Reinstallation
The most obvious reason for such a failure to occur is outdated version Skype. It is initially set to auto-update, but the feature can be disabled. It can, of course, be reactivated. But the best solution There will be a complete reinstallation.
Method 2: Reset Internet Explorer settings
You can also try rolling back the Internet Explorer browser settings to original state. To do this, open it and press the Alt key. A toolbar will open, click on “Service”. From context menu call the “Browser Options” element.
There you need to go to the “Advanced” section and activate the “Reset” option. A confirmation window will appear, click the “Reset” button again. All that remains is to restart the computer. 
Method 3: Deleting program files
In a number of situations, the problem, although related to Skype itself, cannot be solved by a simple reinstallation. This happens because when you uninstall the program, some files are not erased, and the failure occurs precisely because of them. Accordingly, if previous methods did not give the desired result, try the following:
Sometimes users may experience the following error: Skype could not establish a connection. Why is there such a problem with Skype?
The fact is that when launched, after entering the login and password, the program sends data to the server, where information about all users is stored.
If such an account is found, the login is performed, otherwise the program simply does not log into the account.
But the error “The connection could not be established” means that the program cannot contact the server at all - the signal from the program is sent, but does not arrive at the server.
That's why the account menu in Skype doesn't open.
So, we have already figured out what the error “The connection could not be established” means, now it’s worth understanding what to do.
Solution #1. Checking your Internet connection
First you should check whether there is an Internet connection at all. Maybe the problem is not with Skype. This can be done by opening a website in your browser, for example, Google.ru.
If the site does not start, then you should check whether there is enough money in your account to use the World Wide Web or call the technical support of the company whose client you are.
Solution #2. Check program version
Another basic problem is that the old Skype is installed.
To check your version, you need to select “Help” in the toolbar and click on “About Skype”.
In the window that appears, you can see the version (underlined green in the figure below).
Therefore, you need to try to turn it off, at least for a while.
To do this, go to the same “Control Panel”, where select “System and Security”.
After this, you need to click on “Windows Firewall”.
Now all that remains is to check the boxes “Disable Windows firewall" - 2 times (circled in red in the figure) and press the "OK" button.
Now you need to try to launch Skype and if the program again writes: “The connection could not be established,” you can try further ways.
Solution #4. Disabling antivirus
To exclude this option, you should go to your antivirus program, look in the settings, for example, “ parental controls" or others additional functions Skype antivirus.
To exclude this option, you should temporarily disable the antivirus - if Skype works with it turned off antivirus program, that means that's the problem.
As for how to disable the antivirus, it all depends on the specific program.
In Kaspersky antivirus this is done as follows: you need to click on the Kaspersky icon Internet Security right-click and select “Exit” (underlined in green in the photo below).
This approach is applicable to almost every modern antivirus.
It is possible that the antivirus automatically added Skype to the list of blocked programs. How to fix this problem?
It all depends on the specific antivirus. If it is possible to reset it, do so. You can also remove the antivirus.
This is done in exactly the same way as described above for Skype.
Solution #5. Router settings
If Skype says “The connection could not be established,” the reason may be in the router settings. To remove this error, you must do the following:
- Go to the router settings. To do this, type 192.168.0.1 in the address bar of your browser (depending on the router, this address may change, see the information in the documentation).
Advice! You should go into the router settings via Google browser Chrome, Mozilla or any other, but not through Opera - settings very rarely work through this browser.
- Depending on the router appearance of this window may be different. If nothing has changed in the router settings before, the login and password will be the same – “admin”. Enter and click “Login”.
- After this you need to find the item “ Virtual servers" Depending on the router model, this item may be located in different menus. For one of the most popular routers today, DIR-300NRU, the search looks as shown in Fig. No. 12.
There you need to go to the “Firewall” item in the menu on the left, and then “Virtual servers”.
- After going to the “Virtual Servers” item, you need to find the “Add” button. We remind you: the names of the lines may vary depending on the router model. There in the “Name” field we write skype or whatever we want (underlined in red in the photo above).
In the “Port” field (“External port” - underlined in green), write, for example, 4960. Save the received settings. To do this, find the “Save”, “Change” or something similar button on the page. - Now you need to open Skype and go to the settings menu there. To do this, go to the “Tools” item in the top menu of the program and go to “Connection problem...”.
- Here in the “Use port” field we write the port we specified in the router settings. We indicated, as we remember, 49660. Click “Save” (circled in green in the figure below) and try to log in again.
Solution #6. Removing appdata
Sometimes the problem may be that some old data is preventing the program from working smoothly, so it needs to be deleted.
To do this we do the following:
- Go to the “Start” menu and “Run” or press Win + R at the same time. In the window that appears, write “%appdata%\skype” and press Enter.
- After this we see a list of folders and files (highlighted in green in the figure above). Select all of them and delete them.
- After this, we launch the program again. If Skype still doesn’t work, you can remove it and install it again using the method described above.
The video below shows exactly this method. It shows you how to go to your Skype save folder and install the new version.

Skype could not establish a connection - 6 solutions to the problem
Internet messenger Skype is the most popular program for users to communicate online. With its help, you can make voice and audio calls, exchange text messages and files, organize online conferences and even call landline and mobile phones. The main advantages of this program are that it is free, simple and has a high level of security.
But even such a reliable and high-quality tool as Skype cannot guarantee that at some point its operation will not fail. Problems with the messenger are not such a common occurrence, but they still occur. One of the most common is network connection failure. The error that appears is that when logging into Skype, it says that the connection could not be established.
The causes of the problem can be different, related both to global network settings and to the program itself, which happens much more often. At the same time, Skype usually does not connect to the Internet, although there is Internet, and other programs that use it connect perfectly to it. Let's figure out why Skype sometimes writes “The connection could not be established,” and what can and should be done to restore its normal operation. We will move from simple to complex.
Temporary unavailability of the service
It's unlikely, but it could be that your ISP, network administrator (on corporate computers), or even your own firewall is blocking access to Skype domains. Then it is not surprising that the user cannot log into Skype. To exclude this possibility, go through Internet Explorer (!) to the page www.skaip.su/proverit-dostup-k-skaypu and click the "Check" button. The status of all servers should be “Connection successfully established”.
If a connection could not be established for at least one of the servers, this will indicate one of the three reasons listed above.
If everything is in order with the firewall (how to check it below) and Skype still cannot establish a connection, contact your system administrator or contact your Internet service provider's support service. We also recommend checking the functionality of the Skype servers themselves on the page www.skaip.su/status-serverov-skayp. The servers must have the “Working” status, otherwise you need to wait until the technicians themselves fix the problems.
Outdated version of Skype
By default, Skype is updated automatically and this is important, since the correct operation of the messenger on the local computer directly depends on server services.
If you are using an older version, at one point the program will not be able to connect to the remote host, and you will receive the error described above. It is not difficult to determine the version you are using, you just need to select it in the main menu Help - About Skype.
You can also check availability there. new version applications.
If your messenger is out of date, go to the official website of the developer and download the current version. Close the broken program and run the web installer. The latest version will be downloaded to the PC and installed immediately, while the old version will be deleted. If installation problems occur, it is recommended to completely uninstall Skype, including the user directory %userprofile%/AppData/Roaming/Skype, and then clean the registry with CCleaner or another similar tool.
Note: Skype folder, more precisely the main.db file in the directory AppData/Username, contains correspondence history. If you don't want to lose it, create it just in case backup copy, but in general, for starters, try limiting yourself to deleting the shared.lck and shared.xml files.
Outdated version of Internet Explorer
Since Skype desktop uses MSIE components, the connection error may be related to the Internet Explorer browser. It is noted that in some cases Skype does not work and says “check your Internet connection” in Windows with the sixth and seventh versions of IE. For a successful connection, at least the eighth version of the standard browser must be installed on the system. Please update your built-in browser to version 8 or the latest version available for your OS.
Resetting IE settings won't hurt either. To do this, open its properties (via classic panel controls or by pressing Alt and selecting Tools – Browser Options).
Next, switch to the “Advanced” tab in the window that opens and click “Reset.” Before resetting, we recommend checking whether the SSL 2.0, SSL 3.0, TLS 1.1, TLS 1.2, TLS 1.0 checkboxes are checked in the same tab. If not, install the birds, restart the browser and check the operation of Skype.
Blocking by firewall or antivirus
If you are using a built-in or third-party firewall, try disabling it for a while.
Restoring the connection will indicate that Skype is blocked by a firewall. Disabling this protection completely for the sake of Skype alone is not the best idea, but you can create a separate rule for the messenger that allows incoming and outgoing connections. You should also check whether Skype is accessible in the settings for allowing interactions between applications and components.
At the same time, it’s worth checking your antivirus’s “loyalty” to Skype and, if necessary, adding the application to its white list.
Action of viruses and modification of the HOSTS file
The cause of the problem may be a banal virus that has overwritten the contents HOSTS file. Carefully scan your system with an antivirus program, check if there are any specified file"left" servers. The HOSTS file is located at C:/Windows/System32/drivers/etc, you can open the file itself with any text editor.
By default, the contents of this file should look like the one shown in the screenshot.
If there are any addresses listed below, delete them.
Ports and proxies
If you use IP address spoofing programs on your PC, temporarily disable them or create (if the appropriate option is available) an exception. Users who have previously configured a messenger connection through a proxy should check the validity of the IP address and port. Skype will not work and the connection will not be established if the port is blocked or has low throughput. We remind you that the proxy settings are changed on the “Connection” tab in additional settings applications.
For correct operation messenger, ports 80, 443, 3478-3481 UPD and 49152-65535 UPD+TCP must be open on the computer. Check them in any online port scanner, for example, 2ip.ru/check-port and, if any of these ports are closed, open it by creating a separate firewall rule for it or a group.
Interestingly, some users reported that the connection was restored when they unchecked the boxes that allowed the use of ports 80, 443 and the upnp protocol. Try this option too.
Router settings
Incorrect router configuration is another reason why the “Connection could not be established” message appears in Skype. The ports may be blocked in the network device. To enter the router settings, go to the browser at 192.168.0.1 or 192.168.1.1, the default login and password are admin/admin. In most routers, the subsection you need is called “Virtual Servers,” but there may be another name. For example, in D-Link it is “Firewall”.
Virtual servers or VPS are a special service that simulates the operation of a real physical server. On a single computer, it provides complete and independent control over local network and can be used as part of the setup various restrictions, for example, parental controls. In theory, the “Virtual Servers” subsection should be empty. If there are already settings there, try to find out who made them and for what purpose. Perhaps you yourself ordered this service from your provider and forgot about it.
Pay attention to the “External port (end)” parameter. Let's say it's 49650.
So, this value must be specified in the additional Skype settings on the “Connection” tab, namely “Use port [number] for incoming connections.”
If the “Virtual Servers” subsection is empty, you can create your own VPS to resolve the Skype connection error. In this case, we take the values for the start and end external ports from the range 3478-3481 UPD and 49152-65535 UPD+TCP. Select the appropriate protocol.
Perhaps this will be interesting
Above, we looked at the main causes of problems and learned what to do if Skype writes “The connection could not be established.” Most of the tips offered concerned the desktop and portable versions of the messenger, but this program also has a web version that can be used in IE, Chrome and Firefox. It is available at web.skype.com. In general, the web version duplicates the functions of the desktop version, but for it to work correctly you need to install a plug-in. You will be prompted to install it when making your first incoming or outgoing call. If you have Windows 8.1 or 10, do not forget about the universal version of the messenger.
does not connect, what to do, will be relevant, it seems always. Indeed, despite the fact that Skype program in general, it’s not bad; it, like all other applications, cannot avoid failures and problems in operation.
What to do if Skype does not connect
Generally speaking, there can be a lot of reasons for this. And, as they say, “behind the scenes” it is very difficult to advise anything definite in this case. This is about the same as answering the question: My computer is broken. What should I do?..
However, we can describe the most common connection problems and methods for solving them:
- Problems with Internet connection. Perhaps this is precisely the reason for job refusal in the vast majority of cases. Skype assumes that you can start working only if you have a reliable connection to the Internet. So, first of all, you should check the availability of an Internet connection on your device;
- Often the cause of failure is problems with sound or video drivers. Therefore, it is necessary to update them to the most current version;
- Oddly enough, sometimes a user forgets his password or login and cannot log into his account. In this situation, you can resort to password recovery tools. The corresponding link appears in the window when connecting Skype to the Network;
- Often users themselves knock down software settings Skype. For example, when working with multiple webcams, people forget to switch between video and audio devices. You need to check which device is “responsible” for the image and sound. This is done in the Menu: Tools – Settings – Sound Settings or Video Settings;
- Sometimes network functions Skype is blocked by antiviruses or firewalls. Of course, you shouldn't disable them. You need to add Skype to the list of allowed or trusted programs;
- Skype may refuse to work even if it needs to be updated. You can check for updates directly from the program itself: Help – Check for updates;
- You can try rolling back the system to the nearest 100% working restore point.
You can also suggest reinstalling Skype completely. This implies prior complete removal With hard drive everything related to Skype. You can, of course, manually clean the system of unnecessary files and then clean the registry. But it’s faster and safer to do this using third party utilities. For example, the free Ccleaner copes with this very well. After this you will need to download the most latest version Skype and install it. 
If working on a computer Internet browser Explorer, then you can do the following. In its properties go to the tab "Additionally" and check the box next to "TSL 1.0". This worked for some users.
It wouldn’t be superfluous to check if the network settings programs. You can get to them if you go through the following points: Tools – Settings – Advanced tab – Connection section. 
In a word, if Skype does not connect, then this problem is completely solvable. As a universal method, we can advise you to contact customer support for help. In your letter you need to concisely, but at the same time and succinctly describe the essence of the problem, and also, if possible, attach a screenshot of the error message - if one arises. You must also provide the configuration of your PC and operating system, as well as the version of your Skype.
Despite the great popularity of various messengers - Telegram, WhatsApp, Viber and others, Skype remains the most famous and widespread. The application is installed by default with Windows, and can also be downloaded separately from the website Microsoft, which owns the rights to the program. To log into Skype, just install the program, launch it and enter your Microsoft account username/password to log in. If you can't log into Skype, read our instructions, where we looked at the most common reasons why problems arise.
Why can't I sign into Skype?
There are 3 main reasons why you can’t log in to the messenger:
- Forgot your username and password to log into your account. The most common reason;
- Incompatible version of the program with the installed Windows operating system. Despite the fact that Windows and Skype are Microsoft products, there may be incompatibility between them;
- There is a problem with the application.
What to do if you can't sign into Skype
Let's look at how to solve each of the problems described above in order to log in to Skype.
Incorrect login or password
On the Internet, a user has to create a huge number of accounts - social media, mail, various sites and much more. Not surprisingly, there is a high probability of forgetting the password for Skype or any other account. If you see the error “sorry, the login information you entered is not recognized by Skype” when you try to sign in to Skype, you will need to reset your password:
Please note: Skype login and password are also account Microsoft. In the Windows 10 operating system, by default, you need to enter your Microsoft account password to log into your account. Accordingly, we recommend that you try entering your computer password to log into your Skype account before attempting to recover your password.
Installing a compatible version of Skype
Microsoft supports Skype program V current state, constantly releasing new versions of the application, eliminating various bugs and adding new features. It is possible that after one of these updates, Skype simply stops working on your computer or refuses to authorize you, even if you entered your account data correctly. In such a situation, there are 2 ways to solve the problem:
Recommendation: If you already have an operating system installed on your computer Windows system 10, do not disable updates and always keep it up to date. If you are using an earlier Windows version, try to upgrade to Windows 10 as soon as possible to avoid compatibility issues with other programs in the future.
Solving a problem with Skype
As with any program, Skype work a failure may occur. Most often this can be resolved in the following way:
Please note: If the steps described above did not help solve problems logging into Skype, try reinstalling the latest version of the program on your computer by downloading it from the official Microsoft website.
Remember that there are various alternative clients that allow users to communicate with their Skype account. Such clients can be a solution to the problem if the official application does not want to work on the computer at all. One of the most famous alternative clients is Skype Launcher, a distinctive feature of which from the original Skype is the ability to use several accounts at once, which can be useful in a number of situations.
