OBS periodically drops to 0 kbps

I've been having this issue for about a month or so now, possibly starting a bit after I updated OBS 28 and it's really negatively affecting my streams.

What usually happens is that a stream will go on like normal anywhere from 30 seconds to 3+ hours until I notice the red square in the bottom right corner and see that OBS has dropped to 0 kpbs. The first time it happened I assumed it was because my pc was overloaded due to playing a new pc game on stream, but every time after that I've been very much within the confines of my pc's capabilities (streaming console games/games I had no issues with previously).

I've been running OBS in Admin mode for most but not all of these streams, so I don't think that makes a difference. I'm on an ethernet connection with an average of 90mbps Download and 22mbps Upload, but obviously not able to rule this out as it could be dropping right when I have these issues and then going straight back up. I'm also connected to the best server according to twitchtest.

I've heard some issues arising from firewalls or something but I'm honestly not sure how to address this. I went to my Inbound/Outbound Rules within the control panel menus and saw that all ports for OBS were enabled in Inbound Rules (although OBS Studio appears twice here which I'm not sure if it is a problem). In Outbound Rules I don't see OBS Studio at all. Not very familiar with all of this stuff to be honest.

Here's a link to my log from the 2hr stream that decided to kick the bucket tonight which was then followed by a 6min 1min and then 9min stream after multiple disconnects.


Please advise how I can go about fixing this as I am not sure where to go from here.

The most common issue causing 0 kbps drops in OBS is due to the ISP network failing at some point of itself.
The second cause is due to a plugin or script in OBS or a third party software interfering with the network trafic.

You can test your internet connection against Twitch servers using this tool:

TwitchTest | r1ch.net

Test your upload bandwidth and connection quality to Twitch
r1ch.net r1ch.net
Anything lower than 90 quality is bad. You may want to perform a longer test if the drop happens randomly.

Also check:

Dropped frames/disconnecting/lag? Read this first!

obsproject.com obsproject.com

You still have references to streamFX filters but the pluing isn't there.
Too many browser sources. You can simplify it as you are using streamelements alerts and chat setting them in one overlay.

Hey!

I wanted to hop in here, as I've been having the EXACT issues as OP. Ran TwitchTest, and my results are... horrific. I'll stream in 4,000kbps, then drop to 0, and after a few seconds, back to "normal".

Things I've tried include: new modem, streaming from different computers, older versions of OBS, swapping Ethernet cables. None of it has worked.

Log File for reference: https://obsproject.com/logs/InN723DdSXV0ArEo - ISP is Comcast

Any help would be appreciated!

Try disabling or uninstalling Avast, restart the computer and test again. You can reinstall it later if this don't fix it.
In the twitch test results is clear the rtmp protocol is blocked. The first place to check if your own computer, specially the security programs like antivirus and firewalls. Check if windows firewall is blocking OBS or the rtmp protocol.
Do you have any issue with other protocols like watching a movie, youtube videos, etc? Is the quality of the videos as expected or is degraded?
If everything checks, call your ISP regarding this protocol and if they're blocking it by mistake. This is the most probably cause of the issue as you mentioned testing it with other computers but you need to clear the other local causes first.

Hej, i have noticed similar problem. My stream to youtube is working fine and suddenly is goving down to 0kbps and not coming back. Only what i can do is stop stream kill OBS start it once again and start streaming.

Do You solve Your issue ?

best regards

Greetings! I have the same problem on youtube I can stream even at 13k bitrate while on twitch after 2/6 min it disconnects me from the server without losing a frame!

as an ADSL line I have a 100/100

while I was writing I was thinking since on youtube I use RTMPS while on Twitch I use RTMP! I don't want it to be just a security issue

This issue is driving me crazy.
I have a 30mbps + upload speed soI can’t see the wifi as being the issue.
I get this with YouTube and my custom rtmp.
I am trying another laptop on the next stream but not holding any hopes.
This has to be an OBS issue even though they keep saying it’s not.

Hello, I have the same problem, but the servers I use are 100% good with my internet, how can I solve this problem? It's really affecting my stream, and I can't resolve it.

My bitrate used to recover. now it stays on zero and the stream fails. I have plenty of bandwidth.
I have updated my laptop and moved to vmix. I haven't dropped a frame since.
It may be a network issue but it seems clear that OBS can't deal with the problem.
I make my living live streaming. I can't continue to have it fail.
Have a look at the CPU usage while streaming as well.
I found random processes starting that dropped the bitrate.
Just disable the un needed ones. Disable your anti virus as well.
My new laptop has gone from 60% CPU before down to 3% with the new one.
Doing a speed test while streaming will also spike the CPU to 98% and the bitrate will drop.
Don't get me wrong. I love OBS but I can't continue to worry that my stream is going to fail.
It is a work in progress.
