Hey Folks 
I’m having a hard time getting online multi player up and running. I followed a tutorial on UnityCookie.com. For some reason I’m unable to connect to the other Users “room”. When I try to connect Unity throws the error message: “Are you sure you are able to connect to the Server?”
I’ve been reading up stuff on this issue for about a week now and I cannot find any solution. I’m using a UMTS stick to connect to the internet, so there is no router that blocks the connections. I’m able to play Unity Multiplayer games online so my Firewall is not blocking in coming connections either.

This is the code I’m using. It is attached to a single object in the scene. Sorry that the code is so long but it is basically the multiplayer menu.
Could you have a look on how I handle the Server functions and tell me whether I made a mistake?
Cheers!
