Describe the bug

After filling out the OAuth code, on the OTP page I request the SMS code, which I receive. However, after filling it out, I get {'err': 'NOK:SN'} in the GUI, plus a traceback.

Could be a issue on Stellentis side since this error is a response from the API, their servers are notoriously unstable... try again after a while.

If you get the same error, you might want to check if you remote services are active, you need the services activated for PAS car controller to work.

Thanks.

Mabye catch the exception, and print some info like "This went wrong on Stellantis server side. Try again?"? Or let psa_car_controller try again if it's a Stellantis API problem?
