I'm having the same problem - I've just created my server and it works normally, only it isn't shown in the in-game server list, nor on Game Monitor. Now, I don't know whether the problem is with that wait time (because the server hasn't been up for 10 minutes in one piece), or I have forwarded the ports incorrectly, which is most likely the problem. What do you suggest; if the problem is with forwarded ports, how can I make sure they are forwarded properly?
Thanks
