Network Frame Drops and Instability if I use Auto Bitrate

This has seemed to start after the latest update.

Nearly every time I start up the stream I would immediately be dropping around 65% of frames on the network. I found as a quick fix if I reset the NIC it would stabilize for a random amount of time (sometimes minutes, sometimes hours) but then eventually I would start dropping frames again.

I use Multitrack Video/Enhanced Broadcasting with both bandwidth and tracks set to auto.

After troubleshooting everything I could think of I finally decided to remove Auto from Bandwidth and set it to 10000. As soon as I started the stream we were nice and stable. I stopped the stream, clicked auto back on, and we went back to dropping frames.

If i set the Bandwidth to 12000 (the value that auto seems to try to be reaching) we go back to dropping frames again as soon as the stream starts.

So it seems like perhaps the auto setting is set incorrectly.

I am currently running a test stream at 10K bitrate and I have been stable for 10 minutes. I am going to continue this test for awhile longer to see if I remain stable.
 
So here is the analysis

Analyzer | OBS

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.

The question I now have is why?

it says insufficient bandwidth/connection stalls. But I have GB internet, and my upload is over 900. It is most likely not the ingest or more people would be talking about this.

Is there any way to confirm if my ISP is perhaps throttling my tcp 1935 upload? It also does not seem isolated to Twitch as streams to YT and Kick both have this issue if I am multistreaming or just going directly.

Discord streaming (obviously not from OBS) works with no drops or other issues).

What is strange is that it seems to come and go. I'm having this issue right now, but while I was troubleshooting it last night after midnight I could not get it to happen again.
 
I've been digging into the Network tracing this morning. When the issue happens I am noticing that we have Unknown(0x0) RTMP which could be just bad RTMP handshake, but I'm unsure exactly how to pull this thread further to know what is going on.
 
Oh I've been using twitchtest, its very very random and spotty, one connection will be 25000+ 100 rating, and then run it again 2 minutes later and it says 1000kbps.

I'm becoming more convinced its something out of my control. Today an hour after my normal stream time (where things were broken) suddenly started working and I went the next 5 hours with no issues.
