Plex basically unable to play any video on local network. Constant buffering and not completing

Plex Media Server
,
1

Server Version#: 1.25.7.5604 (have tried reverting back to many versions 1.23.x.yyyy+)
Player Version#: n/a web, lgwebos, apple tv

Suddenly happening for the past week+ out of nowhere and hadn’t tinkered with any settings. Every single video will take forever to load up, then play for only about 10 seconds before it appears to be buffering, often unable to resume. I had originally thought it was just my LG TV, but turns out it’s every player on my network.

I’m at a loss here. Did I do something wrong? Nothing looks bad on the server as far as I can tell

  • cpu usage very low
  • memory usage very low
  • network bandwidth fine
  • wired or wireless, both should be super fast

Did you forget to add --device=/dev/dri:/dev/dri to the docker container definition?

I have never had that before and it always worked fine. Gave it a try and there’s no difference. I’ve also never had that device added to the container before and it worked flawlessly for years. Why would it suddenly be required now?

Also, as far as I know, this shouldn’t be transcoding most of the videos I’m trying to watch – and it isn’t. At the very least, the video I’m using now as a test case is doing a direct play both video and audio (Video: 1080p (H.264) Direct Play; Audio: English (HE-AAC Stereo) Direct Play). The CPU is basically idle.

tl;dr: that’s not the issue :frowning:

Took a shot in the dark and started poking at my file server.

Turns out that the memory in FreeNAS was absolutely pegged and not freeing up.

Restarted FreeNAS and now everything works :man_facepalming:t2:

I’m having the same problem with frequent rebuffering, making movies almost unwatchable. I don’t know what FreeNAS is but I’m pretty sure I don’t have it and it’s not a factor. Can anyone suggest any other possibilities?
