Virtual Private Network (VPN) is a network consisting of two or more permissible nodes, as well as software that allows you to hide real IP addresses and securely encrypt all traffic. Thus, this technology provides high confidentiality and security on the Internet, and also allows you to visit blocked resources. However, even with proper configuration, sometimes it is not possible to connect to the VPN. Today we will tell you how to fix this problem on a computer with Windows 10.
Important information

The reason for the lack of connection can be a specific VDN server. In this case, try changing it, for example, select another country from the list.
If a third-party software is used to implement a virtual private network, and not embedded in Windows function, first try to refresh it, and in the absence of such a possibility simply reinstall.
Method 1: Reinstalling network adapters
Depending on the equipment installed on the computer (network card, Wi-Fi and Bluetooth sensors), multiple network adapters will be displayed in the Device Manager. There will also be Wan Miniport devices - system adapters, which are just used for VPN connection through various protocols. To solve the problem, try reinstalling them.
- The combination of the Win + R keys call the "Run" window, enter the DevmGMT.msc command and click "OK".
Method 2: Change registry parameters
When using the L2TP / IPsec connection, external client computers running Windows cannot be connected to the VPN server if it is per NAT (device for converting private network addresses to public). According to the article posted on the Microsoft Support page, it is possible to connect between them if you can understand the system that the server and PC client are behind the NAT device, as well as allow UDP ports to encapsulate L2TP packets. To do this, you must add and configure the appropriate parameter.
- In the "Run" window, enter the REGEDIT command and click "OK".
It is also important that the UDP ports are open on the router necessary for the operation of L2TP (1701, 500, 4500, 50 ESP). We wrote in detail on the ports on the ports on routers of different models in detail in a separate article.

Method 4: Disable IPv6 Protocol
The VPN connection can break through due to traffic leakage into the public network. Often, the IPv6 protocol becomes. Despite the fact that the VPN usually works with IPv4, both protocols are included in the operating system by default. Therefore, IPv6 can also be used. In this case, try disable it for a specific network adapter.
- In the search for Windows, enter the "Control Panel" and open the application.
Method 5: Stop Xbox Live
The stability of the VPN connection can influence different software, including system components. For example, according to discussions on the forums, many users were able to solve the problem by stopping the Xbox Live service.
