Question / Help OBS always disconnects from Twitch

[Braffin]

So at this point I feel like I've tried everything I can think of and could find online. It seems no matter my settings, OBS simply can't stay connected to Twitch. Sometimes it fails a minute in, sometimes it lasts for 20. Seems completely random.

I really don't think it's bandwidth: I tried a stream yesterday at a whole 852x480 resolution and 500 bitrate. My upload, according to the task manager, was literally less than 1Mbps. My internet is 50/50 (Speedtest shows about 50/40) and my PC is the only thing on my network (so it's not like someone else is saturating the connection). My PC seemed fine (not a high CPU usage or anything else) and it still failed after a few minutes.

I've tried multiple different servers. I've put in a firewall exception on my PC for the RTMP port and enabled port forwarding for that on my router. Running no antivirus.

I did try streaming to Mixer and that was perfectly fine, at 1080p/60fps/3500bitrate. Not a single dropped frame. BUT, I noticed that it works fine using their FTL service but NOT the RTMP service. But I don't really know why RTMP fails at this point. To me that says that bandwidth, again, is not a problem but there's something going on with RTMP (either on my network, or my ISP (Frontier FiOS)).

In case it helps, here's a pastebin of the OBS log: https://pastebin.com/9JSCv1H0

Can you use this tool before you start streaming and again when it fails please and post the results. Your log file shows a network problem but not during streaming.

I used that when I was initially setting things up and everything seemed fine. But I can try it again. I'm not sure what it'll show though, since these disconnect problems happen sporadically and I'm able to immediately reconnect the stream.

Well, I tried streaming while I was playing WoW and it kept the stream going for 3+ hours (and only ended when I stopped it). I ran a test using that program while the stream was running and got this: https://i.imgur.com/VPw5rHw.jpg

But then, I switch to Heroes of the Storm and barely streamed for 3 minutes before it disconnected. Ran that test again immediately and got this: https://i.imgur.com/QMv1hlh.png

Then I tried streaming while nothing was running (so just a black screen with my webcam) and it still disconnected.

It looks like you are using the Seattle server. In the second image you can't make a connection to the server which is why it fails. Considering you had a perfect connection earlier If have to guess that this is caused by your ISP maybe your connection is being put into Traffic Management. Who is your broadband provider and do they have any traffic management policies?
