SOLVED: Stream buffers but playback never starts

[RubyNinjaThief]

I'm running Jellyfin on debian linux in a docker container, on version 10.10.6. The server is remote. Everything was working fine until yesterday. I was watching on my browser, and when I clicked on a video, the splash image would come up onto the screen, and the loading icon would spin, but playback would never start, even after several minutes.

So far, I have tried a few things. At first, I tried re-fetching the image. I suspected that my storage was too full, so I cleared a bunch of bloated storage. I rescanned my libraries. I enabled hardware transcoding; my graphics card is an Nvidia 1050ti, so I chose nvenc. These were of no avail. I was only able to get one stream going for a few seconds, and that still took a few minutes to load.

Here is my latest playback log: https://pastebin.com/pAH9mxrS

Let me know what y'all think.

What client are you trying to play on? And can you share the main jellyfin log? The ffmpeg log indicates it is just transcoding the audio, and the video is pretty ordinary. Just about all modern clients should be able to play the video without issue.

I tried to play on browser as well as my little Kodi home theatre thing and firefox on my phone. I also had a buddy of mine try it on his computer using chrome. I uploaded the log to this thing since it was kind of long.

Do you have a VPN running on the host running Jellyfin? And can you share your docker compose for the jellyfin container?

[RubyNinjaThief]

ah, yeah I do. It was a ham-fisted approach to getting internet to work on there a while ago, I never bothered changing it. Here's a pastebin with the compose.

Removing Jellyfin's network mode with host instead of gluetun caused the playback to start working again. Solved. Thanks TheDreadPirate!
