This happens if I am playing a movie or tv show at 200kbps or 20Mb/s. I will watch for 30-40 minutes(sometimes more often, sometimes less) or so, then it will just pause, if I wait like 30 seconds it will start playing again, or if I seek to the same location I am currently at, it will start within seconds. It IS NOT A CONNECTION ISSUE. On my end, or the plex server end.
The only concurrency between all my tests were using a chromecast(because that's all I have). But I don't see why that would be an issue.
I also get this in the logs
WARN - [Chromecast] Player: Excessive buffering detected; network
