Thanks for providing all logs! I have taken a look, unfortunately, I can not pinpoint what the root of the issue is. I would guess, it may be related to your network environment, and that would need further debugging on its own.
If the client and the game are affected by the disconnects, then most likely it is related with your network. Maybe a random short interruption of internet by your provider, or random internet hiccup, or if you use WLAN, that is also very prone to having issues.
The worst case: I have heard from at least one other streamer who blamed malicious attackers for making him losing connection to FAF and his game from time to time. I could not approve, nor deny it, and it resolved itself after a few days somehow for now - but it is something to consider. If you have anyone in your family/friend circle who is more advanced with IT-stuff, I would suggest letting that person check your latency/packet drops while you game, so he can narrow down the issue.
When you could reproduce the issue every time when you do "X", it would also be helpful to narrow it down, but I guess it is "random" - which makes it impossible to see any pattern.
Maybe someone else has an idea, in case I overlooked something.
