Summary of the issue you are facing:
I’m encountering errors in my Nextcloud logs related to the “admin” user not being recognized by the backend. These errors occur during background tasks, specifically when running the UpdateSingleMetadata job. The admin user exists and was working before. The server is using Redis for caching, and these errors weren’t present immediately after installation.
Steps to replicate it (hint: details matter!):
I am really sorry, but I can not find it. ,
