Plex become unusable overnight

Woke up this morning and Plex was unable to find my libraries. I checked to see my server was online which it was. I checked the Plex docker logs to find multiple lines of Sqlite3: Sleeping for 200ms to retry busy DB. - thought that was strange so restarted the docker. Seemed to be working fine althought to be honest, the kids just put something on straight away. Few hours later I’m trying to load the Plex Web app locally http://localIP:32400/web/index.html but no media is loading. Nothing really showing in docker logs so check in PMS logs and find lots of warnings and errors around AudNexus metadata agent… Again, seems odd when nothing has changed

There are other errors to like…

if anyone has any idea what could be the issue, it would be much appreciated!

Sounds like it might be a DNS issue.
Have you tried using a different DNS (e.g. 1.1.1.1, or Google’s 8.8.8.8 or 8.8.4.4)?

I think it probably was a DNS issue. I thought the same after some more pondering and changed my DNS servers. Didn’t fix it immediately, but after another restart of the docker it seems to be okay now! Thanks for the reply

Obligatory DNS haiku.
