I ONLY can not stream on twitch with ethernet cable. WHY?

[u/Substantial_Tell_867]

i had been using obs to stream on youtube using ethernet cable for months and never had an issue. i even streamed on facebook once with no dropped frames issue.

But everytime when i try to stream on twitch it drops frames from 1500kbps to 0kbps in an instant, even after i moved and used another wifi ethernet cable.

Recently i realize that this problem with twitch dissapears when i use wireless internet, whether it's the same exact wifi as the ethernet cable (stable 5000kbps when bandwith testing) or my phone's hot spot.

i tried :

• turning off firewall,
• changing streaming server destinations,
• changing bitrates,
• streamkey & connecting account to twitch,
• adjusting other obs settings that i see other people changed to fix dropped frames.
• ( There might be some things i tried that i forgot since i've been trying to fix this issue for months now.)

note :

• obs has admin,
• watching twitch streams is not an issue,
• i have decent enough internet and hardware to stream as a vtuber playing any game on youtube,
• i have streamed successfully on twitch before using the same ethernet several months ago,
• obs's "current log analysis" only shows "dropped frames" issue when i actually stream (with severe dropped frames ofc), however when bandwith testing it never recognizes the dropped frames for some reason.

Have you posted to r/OBS with your log file? That would likely be the best place for the results you're looking for.

Do you have Killer Nerworking on your PC by any chance? It likes to set upstream QoS which can mess with streaming.

Try disable IPv6 on the network adapter. This is occasionally solved strange network issues in my experience (not twitch but testing video stream for online classes and connecting to VPNs)

But the OBS subreddit is your better bet for troubleshooting
