In October 2021, we saw issues logging into Archivematica. Logged-in users would see an internal server error in the dashboard, and we saw this error in the logs:

HTTPError: 401 Client Error: Unauthorized for url: https://login.microsoftonline.com/3b7a675a-1fc8-4983-a100-cc52b7647737/oauth2/v2.0/token

This means the Archivematica client secret in Azure AD has expired. You can tell this is the case when you log into the and see this screen:

If so, follow the instructions .
