My stream cuts out without alert messages with OBS via Steam why ?

[RayJefferson]

Hello, for some time now I've had the unpleasant surprise that OBS has been cutting my live stream without warning me, which is very annoying, especially when I realize it an hour later.
I've attached a log file for this problem.
Thanks.
