How can we help you?

Checking your operating system configuration

1. Add exceptions for NordVPN.exe, nordvpn-service.exe and openvpn-service.exe in your firewall. If you are using windows firewall , please add 6 rules in to your windows firewall.

Here is a guide how to manage firewall rules.

There should be:
3 outbound - one for "nordvpn.exe", one for "nordvpn-service.exe" and one for "openvpn-nordvpn.exe"
3 inbound - one for "nordvpn.exe", one for "nordvpn-service.exe" and one for "openvpn-nordvpn.exe"

If you have any other firewall management software, you should be able to find that option in the application settings.

2. Add exceptions for  NordVPN.exe, nordvpn-service.exe and openvpn-service.exe in your antivirus application. You can usually find this possibility under the settings of the antivirus application.

3. Check if you have all the latest windows updates installed on your machine, as some security updates might be missing and causing the connection issues.

4. Change the DNS servers that are configured:

Please go to Control Panel -> Network and sharing center -> Change adapter settings

There will be a TAP- NordVPN Windows Adapter V9. Please right click on it and select Properties. 
Afterwards select IPv4 and Properties again and then please add our DNS addresses: and .

5. Flush your network stack :

Enter these commands one by one into your Administrator Command prompt ( link to a tutorial on how to lauch administrator command prompt ) :

ipconfig /release
ipconfig /flushdns
ipconfig /renew
netsh winsock reset
netsh interface ipv4 reset
netsh interface ipv6 reset
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log

After that please restart your computer and check if the issue still persists.
