Improve VPN connection stability on Linux


In this article, you will learn what might be the reason for connectivity issues on your Linux machine and how to fix them.

There are many factors involved in making a VPN connection, e.g., your VPN app settings, network settings, other software, type of network (home, public, mobile data), etc. Therefore, it could be that something on your system might not be compatible with NordLayer default settings and cause connectivity issues.

If you notice the connection being unstable on your Linux machine after connecting to NordLayer service, here is what you should try first: 

  • Try other server locations

For various reasons, like server load or technical issues on the server, one location might provide a more stable connection than others. Connect to a different country to see if that makes a difference.

  • Change the default DNS on your Linux device

If your PC is using a DNS from your Internet Service Provider, that might be the reason why you experience connectivity issues. Changing your default DNS to Open DNS is worth taking a shot.

DNS 1: 208.67.222.222

DNS 2: 208.67.220.220

  • Reset network settings.

As a last resort, we suggest resetting your device's network settings. In order to do that on a Linux device, you can follow our separate guide.

  • Disable potentially interfering apps.

Some apps might have taken over network controls on your device. This can sometimes interfere with NordLayer connection.

This applies to anti-virus software, other VPNs, firewalls, and file-sharing apps. If you have any of those, try disabling it. Then reboot your device and see if the connection gets any better.

  • Remove potential safety controls from your router.

Some Internet Providers tend to provide their routers with parental/security controls enabled by default. Log in to your router, look for the security (or similar) tab and check if there are some security features or parental controls enabled. Also, you may want to change the default DNS to OpenDNS or any other that you prefer.

DNS 1: 208.67.222.222

DNS 2: 208.67.220.220

  • Try a different protocol.

You will find three protocols available on the NordLayer client for Linux. If you have noticed stability issues when connected to the VPN, please try changing the VPN protocol and see if that helps.

  • Disable the IPv6.

IPv6 is a networking system that some internet networks might have. NordLayer does not yet support IPv6, so if you have it on your network, connectivity issues may arise.
