Hello, I followed numerous tutorials on how to setup a dedicated server on mw3, but for some reason with my dedicated box, it wont show up on the master server list and gametracker cant tell that it is online. I have dedicated set to 2 and all of that. Here is what I see in the server console:
Spawning map: mp_plaza2, gametype tdef
Initializing Steam Game Server: game port 27015, auth port 8766, query port 27017, gamedir modernwarfare3, version 1.0.0.0
Steam Game Server initialized as Internet Server.
No Steam Master Servers found. Server will LAN visible only.
Steam Game Server connected. Local IP 66.225.195.186, Public IP 66.225.195.186, Game Port 27015
Steam Game Server is VAC Secure
Spawn map (mp_plaza2, tdef) complete.
-----------------------------------
Steam Master Servers found (2). Server will be Internet Server listed.

It says after everything is loaded up that the master servers have been found, but I don't get why it doesn't show up. Please help me

Do you have access to the firewall on the server? If so, have you made sure that the query port was opened (TCP/UDP)? This is usually the issue with getting things to show up.

try +set dedicated 2 in server.cfg

I also experiencing this problem almost 3 days already. I open all ports and port forwarding to my router but still no luck.

I too have same problem, It says No steam master Server found, Server will be LAN visible only , do u have any solution.?
