Issue setting up VPN (importing VPN connection)

I am currently using NordVPN and am having issues connecting a selected server (or any servers) to my network. I followed the guide on the NordVPN website and also followed the guide on this website to make sure i downloaded everything needed

How to install OpenVPN to connect to NordVPN in Ubuntu

The error message i receive when trying to select a server is

“the file ‘…..’ could not be read or does not contain recognized VPN connection information

Error: The plugin does not support import capability”

I seen similar posts about the same issue and saw people restarting their networks or installing extra things but these troubleshoots did not help me solve my issue. I am fairly new to linux so do not know whats the issue or how to solve it.
