I just bought Garry’s Mod off Steam last night and I can play singleplayer perfectly fine. But when I try to play online with a friend I get all sorts of issues.
First off I can’t join my own server by starting a “Create Multiplayer” server. I get a “Invalid Steam UserID ticket error” and it boots me.
Another issue I have is I can’t retrieve not even ONE server from the server list. I have all the filters correct, I’m positive I’m not accidentally overlooking something minor that might cause me to not see any servers.
I’ve tried to have my friend find a server and I try to join his server through steam by “join game” and it will try to connect but then fails by time out.
Please, anyone who can help me I will greatly appreciate it. I mainly think I need to forward my ports or something. But I’m not very experienced with IP addresses and the sort.
