Online session doesnt show for other players

[Demious 23]

Since the problems with creating an online multiplayer session are fixed, I've been able to create a session and setup everything, but now I'm facing a problem where other people cant see my session in the session list.

 

I can see my friend in the friendlist and I can chat with them, so we're both connected through the Steam online system. My session starts up in the briefing room and I can start the flying environment, but other players cant join my session. The same goes for when my friend creates the session and I try to join him.

I've tried to setup a session and wait for my friend in the briefing room, I also started up the flight environment to see if he could log on, but no luck.

I followed a step-by-step guide to setup a session, so the setup process should be okay, but after trying for almost a full day, we still werent able to both get into a session.

 

Does anyone know how I can make my session show up in the session list?
