I don’t see anything wrong in your logs. Agents appear to be working normally, I see one failed request which is happening as expected as the server was still starting up but everything else appears normal.
Maybe you could elaborate exactly on what you’re seeing specifically so I can have more to go on.
I have been encountering a similar problem with Plex.agent.movie and Plex.agent.serie for about a week now on my Debian 12 system. I am unable to correctly associate a movie or series, which was not the case before.
Each time I attempt to make an association, I receive the following error: “[Req#933b] MetadataAgentPostProcessor: failed to find agent for identifier tv.plex.agents.movie”. This is particularly frustrating as it prevents the correct association of metadata with my movies and series.
