Unable to connect to API


When starting our Windows NordVPN application, you may see this error:


This means that the application was unable to communicate with our main server. This may happen due to a variety of reasons, and there's a couple of things you can try:

  • Restart the application
    First of all, the error may be simply temporary. Try closing the app completely and start it again, or reboot your PC.
  • Check your internet connection
    While our application usually tells you if you do not have an internet connection, this error might happen due to a misconfigured connection - for example, the DNS servers you are using may block your access to VPN providers.
  • Check your Antivirus/firewall
    Most Firewalls do not block our application, however a few select may still have issues letting your connection go through - for example, AVG AntiVirus. You can manually configure your firewall to let the NordVPN application connect, or simply temporarily disable your firewall altogether.
  • Try using a different network
    If you're not sure if the three suggestions above are what's causing this error, you can simply take your computer to a friend, and try connecting from their network - if the connection is successful, you can be certain that it's due to your network configuration at home.
  • Contact our Support Team
