Disconnected 2 times Why Please

Please look at this log file and let me know why OBS disconnected 2 times during this stream. We are using t-Mobile home internet box for 90% of our streams and rarely disconnect. We travel as we do sport event livestreams. There was zero drop-in visible bit rate while doing the stream but out of nowhere it dropped 2 times and reconnected relatively fast. I just need to know why so I can avoid this Thanks

simple answer to this question every time it comes up, your connection to the streaming server was not stable. OBS doesn't play any part in this and you can see you bitrate adjusting in log prior to the disconnect because you have dynamic bitrate on.

Ok good answer I did adjust bit rate as I usually do and most streams stay connected. what is your solution to the dynamic setting?

As an IT person, not someone super knowledgeable on OBS Studio and Streaming protocols, using dynamic bitrate is a workaround to an unstable network connection. Best solution - fix your network. The problem is, that isn't always easy, practical, or within the OBS Studio user's control.
LOTS (innumerable) threads on this issue... start with not using wireless technology (no WiFi, not cellular ISP, etc). Then, be aware of overall LAN traffic - is there other LAN (for OBS Studio PC or other devices) upload/upstream data traffic that is causing a conflict? FYI - there is NOTHING in OBS Studio log that will really help... this is network troubleshooting 101, and has nothing to do with OBS Studio. As for why OBS Studio streaming is the only app impacted, and all else on LAN seems ok? When that happens, usually because there is no other unbuffered outbound traffic that is Latency and Jitter sensitive like livestreaming. Web conferencing comes close, but usually uses patented traffic shaping algorithms to work around WAN link instability. Such is possible for livestreaming, but NOT on any of the free consumer services, that I'm aware of. Other than things like OBS Studio's dynamic bitrate, which is again, a workaround, not a fix.

When you drop the bitrate and it appears to work, then you've found the threshold of consistently available bandwidth at that moment. Other traffic can change that threshold ... it is usually NOT a fixed, always true #. And some setups (WiFi, etc) are FAR more variable than others. But just as freeway traffic can vary, so does Internet traffic, and 'traffic jams' can occur, sometimes completely out of your control

Yes My saying is IT'S ALWAYS SOMETHIUNG. Livestreaming is not for the faint of heart. I agree 100% network is always the main thing and never use wi-fi if you can help it. We are always remote and not sitting in a studio with upload speeds through the roof. Usually you can tell if OBS is going to disconnect by monitoring bit rate/ network connection graph. In my last cast everything was steady there was zero indication of any network issue that I could see. I thought the Log File would uncover a situation or setting I was not implementing or neglected. Thank you for your responses! Appreciate all input and assistance.

Unless you work directly in a Amazon datacenter, no one has control of their bandwidth to Twitch (or wherever you're streaming to) once it's leaves their modem.

IMO, I would leave dynamic bitrate on. Lower quality frames are better than no frames. I use to stream pool matches with a 6mbps up, shared with customers, connection and for awhile was manually changing the bitrate during streams to avoid dropped frames. It was such a relief to not have do that anymore.

If the services you're connecting to through restream support HEVC, you may consider using that as it get's better quality per bit.
