@Kevin_Z I have just purchased an Archer VX1800v and can't get it to connect to a NordVPN OpenVPN config. I've tried connecting to a UDP and TCP server that connects fine through the Nord app (Windows). I've looked in the OpenVPN config file and I don't have any sections as mentioned in the accepted response above. When I try to connect using the OpenVPN Connect client, I get the following error message: Which I can get around by commenting out the offending ping-timer-rem command from the ovpn file as below, but I'm unable to get this to work on the tp-link device: The system log doesn't show me (not a network engineer) anything erroneous about the VPN connections.
