Question / Help URGENT: Can't stream on YT, Key/Server error

[TeoGuitarrist]

Hi Guys, yesterday I've tried to stream on yt and in my testing everything was fine, when I should go live this error started to appear

and I wasn't able to solve in any way, the stream key is of course right. After couple of hours I managed to start the streaming as test but today I'm still in that situation, I really don't know how to solve this.
Here u can see the log file.

The log reiterates the error message-- either your stream key is wrong, your computer is unable to contact the YouTube ingest server, or some other issue on your account is preventing you from streaming using your correct stream key.
