rest.ApiException: (401) Reason: Unauthorized

[oknowletssee]

My instance has been running for about 6 months, very reliable. Thank you btw!
A few days ago I realised a downtime of my psa car controller instance I host in docker. After removing the instance, installing and configuring successfully yesterday, I now face the same problem as a few days ago:

psa_car_controller.psa.connected_car_api.rest.ApiException: (401)
Reason: Unauthorized
HTTP response headers: HTTPHeaderDict({'Content-Type': 'application/json', 'X-Global-Transaction-ID': '08f333a567d7ccxxxxxxxxxx', 'Strict-Transport-Security': 'max-age=31536000; includeSubDomains', 'WWW-Authenticate': "Bearer error='invalid_token'", 'Date': 'Mon, 17 Mar 2025 07:17:07 GMT', 'Connection': 'close', 'Set-Cookie': 'PSACountry=DE; Domain=.groupe-psa.com; Path=/', 'Vary': 'Accept-Encoding'})
HTTP response body: {"httpCode":"401","httpMessage":"Unauthorized","moreInformation":"Cannot pass the security checks that are required by the target API or operation, Enable debug headers for more details."}

During handling of the above exception, another exception occurred:

So it seems like the other side all of a sudden rejected my „unauthorized“ connection due to an invalid token, it seems. Am I doing something wrong or has Stellantis changed something in their REST API?
