VPN pop-up

Yesterday I updated my MacBook Pro to Big Sur. After re-starting it I get a pop-up about VPN-connection and having to give authentication-information. I have never made an vpn, so I don’t get where it’s coming from. However under system settings -> network, it says NordVPN IKE under VPN-program. It constantly says “connecting…”, and I can’t turn it off. You should be able to use WiFi without vpn, so it seems like the pop-up is blocking it? My wifi is connected and perfectly fine, but can’t use safari, Spotify, etc. please help!
