OBS keeps dropping to 0 kb/s out of nowhere

Over the past couple days, I've tried to stream and every 20-30 minutes or so, OBS suddenly drops to 0 kb/s, my Discord broadcast ends with it saying 'Stream Paused', my voice connection fails, and Twitch shows my bitrate has completely tanked. This has happened both days I've tried to stream, and only when I've attempted to stream, and it's only gotten worse today. Any idea on what could be causing this and how to get this problem fixed? I'll try to provide any other additional details if necessary.

same thing has been happening to me as well. can happen from 1hr to 3hrs and it will drop. have seen bitrate msg in the lower left of obs when ever i alt tab from game, or game goes into a loading screen. have been using obs for a few years and never had this issue before.

I'm having the exact same problem!

I was streaming and the KBPS just kept tanking to 0! Shortest was 4+ mins and the longest was 34 mins (The 5 most recent vids here https://www.twitch.tv/waydgaming/videos)

Extremely frustrating as everything for me was a-ok in November, and I was away until today, updated OBS and nothing but problems!

Do you know EVERY single device hooked up to your local network, and using that Internet connection, and EXACTLY what it doing? Unless your PC is only device and you know exactly what is running on the background on your PC, the likely answer is no. And that could be your problem (or not)
Are you doing any network monitoring while streaming? Are you doing any local PC hardware utilization monitoring while streaming (ie Windows Task Manager (Performance tab) and/or Resource Monitor) to look for bottlenecks?

@WaydGaming - did you look at your logs... See all those streamelements errors? have you removed/disabled such plug-ins/elements to troubleshoot? I'd remove OBS browser elements pulling anything that isn't local as OBS may be perfectly fine

Hi @Lawrence_SoCal I've been streaming for a few months with no issues with the set-up at all, I was offline for about a month due to being away from home, came back and updated OBS and had the problem since then, so I am fairly confident it's not the set-up but, I will try your suggestion to see if it works (As a stopgap), but I do believe the issue has come about due to the last update :( I do appreciate the reply and giving me some options to look at in the meantime, thank you

This same happened to me today. I was streaming fine till yesterday. The issue seems to be either obs or windows and nothing else. As soon one is alt tabbing or minimising the obs it is going in background and dropping the bitrate to 0kbs. Not able to find the solution tried everything. I was streaming great with the same setup and internet connection from last 7 months. But I updated my obs today and the problem started

You are using 3rd party add-ins with OBS. Are those addins/plugins compatible with the latest OBS (don't assume yes)? or is there a new dynamic with latest OBS update, Windows OS updates, and your add-ins? etc
it may look like you only changed one thing, but this real-time video encoding is hard/complex stuff and you are using a free open-source solution. so.... yea, stuff can break... may or may not be OBS fault/issue... just food for thoughts. I don't use any streamelements/browser sources, so can't comment specifically on interactions

that sounds like an overloaded PC (or you made some OS errors regarding process prioritization??).. or... lots of possibilities. My recommendation for best chance of a focused reply, follow forum instructions and create a new thread, properly titled, and post an OBS stream log

Even after a system wipe and fresh install of the key software I use, still have the same issue. So sadly having to use streamlabs until OBS fixes/updates (Had zero issues before OBS & Windows update). I now miss my OBS :(
 
I updated from OBS v25.0.8 to v26.1.1 this week, running on Win10 20H@ with all latest updates. No issues whatsoever, streaming/recording, etc all fine.

When you say key software, does that include the 3rd party plug-ins/elements I mentioned might be the cause of the problem (not OBS itself)? Have you reviewed your recent OBS logs?

By 'key software' it's just windows, Norton anti-virus, Elgato Wave Link & Streamdeck, Nvidia Broadcast, OBS, Steam (Only games installed so far: Medieval Dynasty & 7 Days To Die) & Discord. I'm gonna give it a while (don't want to be disrupting my stream with 0 kbps issue) before trying OBS again, as I love and miss it!

Thanks for trying to help
 
In another thread, a user had a mis-configured 3rd party A/V s/w (not Norton) that was the cause of the problem
I'm all for security in depth, and not a fan of trusting MS for a security product. But modern A/V has a lot of threat vectors to consider, and makes assumptions that don't always play nice with unexpected use cases. So, might be worth checking into the networking config of Norton, and make sure its not a possible part of the issue (wouldn't mean Norton is to blame, just possible though that an interaction between Norton and ?? has a nasty implication for streaming... worth checking into). The other recent threads with similar issue appears to be related to Windows Update and certain NICs
