I'm having this problem as well, but it's not affecting all my friends who are on steam. I have the GoG version, and using direct connect I can connect to some steam games but not all.
I haven't been able to solve it myself, but the most recurring tip I've seen when troubleshooting is to run the game directly from the .exe and in administrator mode rather than launching it from GoG. Didn't change anything for me, though.
