My computer crashed recently, and I had to reinstall everything. Since then, I could not have anything above 720p anywhere besides playing directly on the computer that runs plex.

It looks like the maximum rate is 2 Mbps regardless of the original format.

I my install is pretty much the same as before.

I run plex as a docker container on Kubuntu.

CPU : I5-4590

GPU : GeForce 1030

I installed the Nvidia toolbox for docker as well, and everything should be good

I tried activating, deactivating HW transcoding, playing with the transcoding speed option, disabled the iGPU to use only the 1030, but nothing seems to make any difference.

I first thought it was a certain format, but it seems to affect everything. I tried to optimize a file by encoding it with the plex option, but the issue stays.

I thought about a network limitation, but nothing is supposed to have changed.

I’m kind of clueless now on what to do next

Any idea on where to look?

Edit2:

Solved!

I unchecked the “use relay” option, and that fixed it.

I still have issues with certain clients, but that’s another problem.

I found it odd that everything defaulted to relay when it could have direct play with certain clients.

Thank you for the help!

    Docker Bridge networks usually have their ports mapped through to your main network so unless it is very misconfiguration that is not where the issue is likely to be.

    I’d look in your router settings for client isolation perhaps. Can a computer on your network ping another device?

    Also if you haven’t already, install tautulli which will give you more detail about what is being played, how and why it is transcoding, and perhaps the problem can be identified there.
