Hello, today I sent out an RTMP stream, that was running for almost 2 hours, until it suddenly stopped.
After restarting the stream and restarting the software it still didn't work.
I got a new Stream-URL and stream key and it still didn't work. After restarting the whole Computer it continued working until the end of the stream.

This is the log:

Any explanations on why this happened and how to avoid it in the future?
Thank you in advance!
