I am having trouble playing certain files on my plex server. Diagnostic files are attached. This is happening with specific files. From what I can tell it isn't a transcoding issue, as other files are being transcoded just fine, and the files in question aren't corrupted because I'm able to play them in VLC media player.
As a little background, I've been having some intermittent stability issues with my server. It would crash in the middle of the night and the mover script would never get run. The stability issues have been resolved and I've manually run the mover script to clear my cache of media files that I put on there that hadn't been automatically moved over.
My observation is that the only files that are having troubles are ones I would have expected to be on the cache and moved by the mover script. My plex media folders are pointing to a plex user share, not the cache or physical disks respectively.
Things I have tried to troubleshoot:
Change transcoding location to multiple places
removed unplayable files from user share, deleted trash in plex, readded them to usershare and retreived metadata.
Proper unraid reboot
restart docker several times
isolated plex docker so no other dockers were running (I was thinking maybe there was a possible deadlock or race condition)
confirmed this isn't a file type issue, unplayable files are mkv's, but other mkv files play fine.
Again I believe i have narrowed this down to data that used to exist on the cache drive but is now on the array. However, like i said Plex is pointing to the user share, not the physical disks themselves so I don't know how this would be a problem.
These files were playable prior to using the mover script. If anyone could give me an idea of something to troubleshoot that I might've overlooked, that would be great.
