This live TV session has ended

Server Version#: Version 4.156.0
Player Version#: (what is this? no idea)

My Plex plays only for some random amount of time and then errors out:
”This live TV session has ended”

Also I’m noticing that the skip back ten seconds button is not really working. Sometimes I can force it to restart at an earlier time, but often it just totally ignores clicks on the timeline at an earlier time.

Seems transcoding might be broken or something. How can I troubleshoot it? My live TV sessions are getting interrupted approximately 100% of the time now.

Under debug I have un-selected “Direct Play” and also “Direct Stream”. Seems to have made no change in the problem. Help?
