Error 5:9 - cant host games online

Whenever I try to host games online I get this error code:

Failed to advertise the game. Connection lost while trying to advertise the game. ((Error 5:9)

Doesn’t matter what server im on or what game / game type etc. , always gives me this error

I have port 6112 open, firewall shouldnt be problem, anti-virus no problem

Im going to reply, eventho its months later.
Havent had any issues until today, after the newest patch.

“failed to advertise the game (5:11)”

this just started happening again, plus there are many “open games” that are unjoinable

is the problem has been resolved? I’ve the same problem …
