Around 9pm last night, my Plex server seemed to crash about 2 minutes into an episode of a tv show I was watching. When I took a look at the logs, the only error I found was related to a bad local network IP address, so I rebooted the docker and fixed that. Again, 2 minutes into the show it crashed, so I rebooted the docker again and attempted to stream something via the browser. Same show crashed the docker a third time, so this time after the docker reboot I tried a different show. Same result. After about 20 minutes, the problem seemed to go away, and I was able to watch the show. I thought this was a minor blip, but today around 1pm the exact same thing has happened, yet services have not yet been restored.
In the above link, it seems several users have experienced the same behavior that I have. I’ve included a screenshot of what the local link to Plex in my browser looked like right at the docker restart, which I’ve never seen before.
