I have tried to restore all my plex-related files to before everything crashed, back to the 3rd of october. I created a completely new container and let it run.
Still nothing. The server is completely unreachable, and from what I can tell no new logs have been created, the last timestamp now being 2nd of october. This makes sense as I rolled back a day before the 4th. I think there is something very wrong with the 1.18.0.1846-f62172e99 update process. It seems I’m not the only one having issues: Plex server update 1.18.0.1846-f62172e99 is borked
