Hi. After a Server reboot, All I get is Conversion failed. The transcoder exited due to an error.

In this log I tried it with Moana, but I have it with everything I try to play.

Anyone an idea?Plex Media Server Logs_2021-01-27_18-07-00.zip (2.6 MB)

The server is having a problem with this source path.

Did your machine install updates recently?

3

Yes, I actually updated Plex and Ubuntu, this happened short after.

4

I suspect Ubuntu. It looks a lot like a file system error with UnionFS. “input/output” error is a fairly “smoking gun” in this case.

Cam you check by manually launching a FFMPEG session to a dummy output file?

5

Somehow it started working out of itself again. No clue what it really was.
