Switching over to the NORD Service credentials fixed this for me.
Apparently this email went out:
Due to the recent change in the authentication process, using your email and password for the manual connection method will no longer work. You will need to use the service credentials instead.
You can find your service credentials by following these steps:
Please log in to your Nord Account by following this link: https://my.nordaccount.com/dashboard/nordvpn/
Click on the NordVPN tab on the left panel which is under the Services tab.
Scroll down and locate the Manual Setup tab, then click on Set up NordVPN manually:
Verify your email by entering the one-time code you will receive in your registered email inbox. If you are unable to find the email, please make sure to also check your spam/junk folder.
Copy your service credentials by using the buttons on the right.
