A way to rule out network issues.

[Bar_be_que]

Hi everyone, i recently started having some issues with streaming to twitch, the constant bitrate of 6000 upload always showed green in obs studio. Recently I can't stream past 3.5mb upload and obs is saying that is best I can do however upon doing speed test and knowing my upload is 70mb via a speed test is there a more better way to do some trouble shooting on my network to rule out if it's my ISP throttling me, If my network is taking under load of the upload for some reason? Any network people around know some times I can check besides just the green square box in obs saying oh you're going into the red while uploading. Thanks.

Speed tests are cute... and a rough guideline, but do NOT indicate a consistent threshold/floor of bandwidth.
1. I recommend monitoring at OS level (NOT OBS stats) to check outbound traffic and ensure consistent with what you think OBS is sending. Does it match? if not, time to investigate
2. Then monitor at router level for same thing. You need to make sure you don't have (unexpected) bandwidth contention.

Have you tested using R1ch's TwitchTest tool to check your connection to the servers; you want a Quality score of 100, preferably. https://r1ch.net/projects/twitchtest

Very well on that info. So yes the r1ch tool I used about 6 months ago and wasn't having any issues then and found a chicago server was best with a round trip of like 40ms if i remember right and 10000 max upload the tool said. I don't know how to monitor traffic at the OS windows level. I can figure it out with some direct and or software to use if you could recommend some? Also for giggles I started a facebook stream just to see if obs showed it falling on it's face at 6mb upload which is always my setting to twitch. Low and be hold it's just fine. Would that be enough to indicate that it's twitch then since i tried another service and it was fine? Should I do another test anyways with rch1 and see. I think i will now for fun. Just to rule out a in between. Any local software or guides on how to monitor some traffic on the windows level still and i'll research it. Thanks.

Well just did a test with the tool again and wow. So most all the servers in my area were only allow 3980 to 5800 max upload. The first time I ever used this test I was getting 10000 mb upload to some servers and others were at the 8000 mb range. So now how can i tell from here if that is my ISP or twitch that is limiting a bit from maybe some problems or what not? Next to testing like I did with facebook where i was able to not have the stream fall below my max 6mb upload.

check you network settings and firewalls when you use a thirdparty firwall deinstall it defender make the same job ! did you use an VPN disable is and check your ip settings in obs ! bind it to you real ip

Was away for a bit, I found later by using the test r1ch that no matter what account I used for twitch to stream to i was limted to 6000 upload, I had my brother do the test as well with his log in and same results, it seemed that day twitch was throttling all uploads to 6000 for some reason, About a week later i was still having issues, Ran the r1ch test again and upload fixed, Shows max 10,000 like it should. So i belive the problem to have been on twitch side since I, my Brother, and a other friends had the same issue on twitch streaming those day.

Twitch limits your bandwidth to their ingest servers at 6000kbps, which is recommended anyway at 1080p.

is there a more better way to do some trouble shooting on my network to rule out if it's my ISP throttling me

Testing with VPN running and without VPN running would give you a better picture on whether your ISP is shaping your internet.
Also, during test streams, monitor your router, depending on what router firmware/software you're running. Some routers will let you know whether you're network is being congested, or other issues that may factor into your upload loss.

Keep another device using the same network up to rule out your LAN.
