Connecting to NordVPN on my GL-AR750

Hi, I’m trying to connect to my NordVPN on the router. I downloaded and uploaded the config and it says success. When I hit connect, it says “Conflict! All other VPN connections must be stopped first” - I am not on a VPN but I do have the NordVPN app on my phone. Could this be causing it? Thanks!

You enabled vpn server?
