Recent Encoding Overload Issue with Enhanced Broadcasting on Linux

[pixie_laluna]

Ever since Enhanced Broadcasting finally in Linux, been streaming with no issue. However the past week, using the same settings, OBS keeps disconnecting and reconnecting, showing an “Encoding Overload” warning. The moment I click Start Streaming, the Encoding Overload appears immediately in the OBS status.

During today’s stream, I was disconnected more than 20 times. It is important to note that this issue started only this week, and I haven’t installed any OBS updates during this period.

OBS version : 31.1.2 (flatpak). Error log is attached.

What have I tried :

1. During streaming, no other apps are running besides OBS and the game, so the GPU isn’t being used elsewhere.
2. Streaming preset was originally set to P6 Slower (Better Quality). I tried changing it to P5 Slow (Good Quality) and P4 Medium (Medium Quality), but the issue remained. Also, the Enhanced Broadcasting options freeze these presets anyway
3. At one point when I got the warning, followed by "Reconnecting", I immediately checked CPU and GPU temperatures : CPU = 80°, GPU = 59°. The GPU temp wasn't even that "overloaded". In case this info helps, GPU is Nvidia RTX3080.
4. Lowered all in-game settings to the lowest render quality and capped the framerate to 60fps. For info, I have been playing the same game before and after this Encoding Overload issue start appearing, and the game is a lightweight 2D platformer, not demanding on the GPU.
5. Uninstalled the DistroAV plugin. It wasn’t in use in my streaming setup, but logs showed it was loaded, so I removed it.
6. When Enhanced Broadcasting is disabled, the problem is gone.

It is crucial for me to keep using Enhanced Broadcasting in my streaming for reasons that too long to elaborate here. This Enhanced Broadcasting option is only available via Flatpak, so far. Therefore, switching to the apt version of OBS or disabling Enhanced Broadcasting is not an option. Any suggestions to troubleshoot this ?

I did not multi-stream and this happened starting just this week. I have been using cable connection with no issue so far. Here is a screenshot of speed test I did just now. I live in a country with really excellent internet, and based on the speedtest results too I doubt that the connection is the problem.

Also, I posted this same question on other platform. Someone suggested to change Settings > Advanced page, scroll down to Network > Set IP Family to IPV4 only, since my log shows it's using IPV6 which some ISPs handle badly. It seems to be working so far, I did a bandwidth testing with no issues.
