Plex Media Server

Server Version#: plexmediaserver:amd64 1.20.3.3437-f1f08d65b

Newest update broke plex.

Following another post’s formatting, which seemed to get a workable fix:

(Installing over same version, to check for better result)

Downgrading to PlexMediaServer-1.20.2.3402-0fec14d92 did fix the issue

Edit: Plex is, now, crashing even on PlexMediaServer-1.20.2.3402-0fec14d92

Edit 2: PMS is now intermittently crashing and restarting

May I have the Plex logs? (Settings - Server - Troubleshooting - Download Logs)

/etc/default/plexmediaserver is not used on systemd systems

Which post do you refer to?

3

I just updated as well to 1.20.3.3437-f1f08d65b on qnap x86 64, and now plex no longer responds. it is started, but, the /web/index is no longer found.
edit, found this in the log, and also, the crash uploader was triggered.

I am going to try a reboot first.

EDIT
Before rebooting, i noticed i could still access plex with the android app, browse everything, even being to start casting. but, after casting something, i get a “sorry!, conversion failed, the transcoder exited due to an error”

Edit, video still plays on my phone, just not casting.
when trying to access the web gui, i get the normal message about accepting the security Cert, but, after excepting, get a 404

Edit, I tried reinstalling the qpkg, that didn’t help.
but, after a reboot, Plex web loaded fine.andriod app works fine, casting fine.
I suspect that on the upgrade the program listening on that port plex uses 443? that it didn’t shut down properly and wouldn’t allow the upgraded one to start.

@chris.roulston

It restarted too quickly and got itself in trouble.
There is an update coming for that.

If it’s been stopped for a while now, it will restart cleanly.

7

I tried stopping the service, waitting like 10 min, then starting it. That didn’t help. I had to Reboot. But, like i said, it is working fine now.

8

I have problems too with this update. Rebooting qnap now. Hopefully that works. Otherwise I have to downgrade plex.
