Plex on UnRAID disappears daily

Server Version#: 1.42.1.10060
Player Version#: All, the player does not matter

Been having a problem for a few months now where my UnRAID based Plex server seems to disappear once a day. When I open either the web app or on one of my TVs, I won’t be able to see the server until I bounce the container. Once the container is restarted, it’ll work perfectly again. I think this started with an update but can’t say for sure, it’s been happening for some time now.

UnRAID version 7.1.4

Running Plex as a Docker container, using the plexinc/pms-docker repository.

Logs attached.

Any ideas or suggestions for what to try? I was able to get Plex updated to the latest version but still having the same issue, it just seems to “die” 1-2 times a day. Restart the container and it comes right back and it never dies when watching content.

I’ve updated to 1.42.2.10156, same issue, Plex just seems to disappear randomly. Restarting the container immediately brings it back. What’s really strange, I can log into the Plex interface on the UnRAID server and it shows the login screen correctly and lets me in, but cannot see anything on that server, my other Plex servers show up, but even logging in directly to the local IP address, for some reason, the server doesn’t show until I restart the container.

See anything in the logs that’s of interest?

I’ve been having exactly the same issue as you. On Unraid, using the official container. Seems to have been going on for a couple of weeks for me. Currently on 1.42.2.10156.
At least once a day, my server will disappear.
Can’t see it remotely, or locally.
Home screen just shows my account, Plex web settings and then a blank area where the server should show.

Strangely, I can sometimes open the Plex app on iOS and can see the server and play content at the same time that my server “disappears”, and friends and family have commented that it’s missing.

Like you, a restart seems to fix this every time and it’ll stay up until me or friends/family notice it’s gone again.
Never seem to notice any issues whilst content is being played either.

The behavior is very similar for me, but it occurs much more frequently! Usually, the application just seems to die every few hours.

The only difference is that I have a UnRAID system, but an Asustor NAS with Plex installed.

Version: 1.42.2.10156

Happening to me too… im running on ubuntu via docker. nothing is logs at all. Its like it disappears and when I restart container it shows back up.

I am stumped as I built a new plex server and its doing this but old one is perfectly fine… no difference between 2 besides the root folder of where everything is stored.

After lots of head scratching, I figured out that it was the Kometa (formerly Plex Meta Manager) docker instance that was crashing my Plex server every day.

I hadn’t realised at first that Plex was going off every morning at 6am - when Kometa runs. I would only notice it disappeared at random times of the day.

I tried all sorts:

  • Creating a new test Plex instance - which didn’t suffer any crashing issues.

  • Moving to BinhexPlex container (copying all app data from the old one)

  • Excluding Plex container from nightly backups

  • Changing timings of Plex scheduled tasks.

Plus more, that I’m forgetting right now.

Then thought I’d try turning off other containers that interact with Plex. Starting with Kometa.

For 4 days running, Plex stayed up.

I triggered a manual run of Kometa one evening and Plex dropped at the end.

I checked the config.yml for Kometa and turns out it was using an old X-Plex-token. It seems that Plex doesn’t always cleanly reject invalid tokens, so looks like it was still allowing Kometa a connection using the old token, and this seemed to be causing Plex to crash. Kometa seemed to be working fine and doing its job each day, so I had no reason to suspect an issue with that.

I updated the .yml with the new token and Plex has been working perfectly for 3-4 days now. No crashes.

During the September Plex “security incident” where we were all told to reset passwords, I chose “sign out connected devices”, which I assume prompted the token change.

This may not be the same issue for everyone, but may be worth checking if you have anything else that interacts with Plex which could be causing this. Especially if it’s potentially using an old token to connect.
