Bitrate is stable for a while then goes wacko

I've been having a problem lately. I'm streaming to Twitch at 6k bitrate and I'll be streaming for a while and playing a game and then after maybe an hour to two hours I'll see that the bitrate is going up and down to 0 and obviously I start losing tons of frames. I've tried closing nord vpn entirely and testing my speed at speedtest.net, and while speedtest.net is always giving me the same fast and stable speed, this is not reflected in OBS. I've seemed to have fixed it temporarily by closing and reopening OBS when this happens and most of the time that will fix it for a while. But it's still pissing me off as you might imagine and I just can't figure out what's causing it. Thanks in advance for any help.

I could still use some help with this issue. I have stable and fast internet speed always but OBS bitrate is all over the place. I really can't make sense of it. I only started having this problem over the past weeks to a month. Any help would be great. Thanks.

I also got a log saying max audio buffering.

1. In many cases, wireless connections can cause issues because of their unstable nature. Streaming really requires a stable connection. Often wireless connections are fine, but if you have problems, the first troubleshooting step would be to switch to wired. We highly recommend streaming on wired connections.
2. If you are still having dropped frames with a wired connection, use the x264 encoder as the AMD/AMF encoder does not support Dynamic Bitrate.

I'm confident in my wireless connection. It's impossible for me to run a wire in my current situation, but my internet speed is extremely consistent. I was streaming for a few hours without much issue and then it seems to happen out of nowhere. I now have woken up after several hours after the issue had forced me to discontinue my stream, I am testing the ingest servers and the problem is not occurring now. I haven't changed anything at all. It just works now. Then at some point it will start having problems again. I am already using the video encoding that you mentioned. If it's helpful my internet speed is always at 50Mbps down and 10Mbps up. I have the bitrate set to 6000 and I easily keep up with that with no issue, until of course my mystery problem kicks off.

I will run my stream privately so I can get a full log of before, during, and after. I'll leave it running until the problem surfaces.

Okay there's a new log. I'm not sure what "Max audio buffering" is but I'm thinking that may be my issue. Or at least part of it perhaps.

1. Run OBS as Administrator. Right click on the OBS shortcut, properties, advanced, check box, ok, apply, ok.
2. I'm 99% sure that x264 supports Dynamic Bitrate. Re-enable that.
3. The things causing Max Audio Buffering are not going to cause dropped network frames.
