Hello everyone, I got a weird issue i'm trying to tackle but can't figure it out myself (unless it is a bug in Plex).

I got several shares that my dockerized plex server has rw access to.

most of these shares have the owner nobody and everything inside has rw access for user/group/other. A few of my shares have the owner root (was this the original owner a while back?)

I'll stick with two shares:

Concerts (video)

Concerts (audio only)

Both shares have owner nobody in unraid, mapped rw in docker and Plex sees the files just fine.

Thing is, I can play video files that are in the root of the video share without any problems (mp4/mkv/webm), however, my audiofiles (mp3, opus) stored in the root of my audio share, which are found by Plex, cannot be played at all. sometimes i get a generic playback error: An error occurred loading items to play.

As soon as I move these audio files to a subfolder (and rescan my library) plex is able to play them without any problem.

I can't figure out why this is happening. Is this a bug in PLEX or is there actually something wrong on my share settings that I'm overlooking?

ok, probably should have checked the plex forum as well. Thought it was a user/configuration error on my side. Guess not.

stop the docker
and run Tools

you esentail need to tell the uraid host to use proper file group other permissions

cd /mnt/user/plexdata
chmod -R 777 *

chown nobody:users -R *

this solved the issue for me. Thank you so much!
