Random bitrate issues when starting streams

Hello all. Our church has been using OBS to stream services, and for the last few weeks we are experiencing a lot of issues. Lately we are needing to start and stop our OBS stream dozens of times before our bitrate will go green. Often we need to stop and start the stream over 15-20 minutes to get it to work.

For example, we will start streaming, and the bitrate goes red right away at around 500-2500kbps. Our bitrate is normally set at 13500kbps to stream 1440p60 to YouTube. The stop/start cycle continues until randomly a start will see our bitrate go straight to ~13000kbps mark displaying green, and it will stay that way for HOURS. However, if we stop at any time during that period, and start again, it'll go back to red.

Our ISP is Spectrum business and sees about 200-300mbps download and around 150mbps upload on speed tests. I have no real way of testing stability and minimum upload speeds, which I know are important, but streaming at a bitrate of ~13000kbps on a connection with an upload speed of over 150mbps shouldn't have any issues!

A log file from our recent Sunday service is here: https://obsproject.com/logs/khSJK14B6gnEcgMV

Note the connection stalls/bandwidth errors. I'm just not understanding the why.

A few additional details:
- Video and audio are coming into OBS from an NDI output from ProPresenter 7 (video and audio are provided to PC/ProPresenter from ATEM Mini)
- PC is a hardwired ethernet connection
- OBS is running as admin on the PC
- No other processes are running on network/PC during service
- Speed tests during these periods show high connection speeds

Any help or advice would be greatly appreciated!

Okay thank you for the reply.

I did just change to use NVIDIA NVENC H.264 instead, and the same issue persists.
