Wireguard ACTION=REKEY-TIMEOUT after changing Mullvad account number

I recently changed my mullvad account to a new number. I tried to update the account number using the WireGuard Client dashboard, but I still just always receive this error. Is there another config that I need to update to move to the new account?

Personally speaking I don’t trust the built in ‘Mullvad / AizireVPN’ ‘helper functions’ as changes to the VPN provider’s infrastructure are known to break as GL lags behind updates… one change on their web site/authentication system renders the GL helpers useless.

Pull down new confs fr Mullvad & manually upload 'em to GL GUI → VPN → WireGuard Client → [create new group] → Add Configuration.

Delete the old confs once back online.
