One of the following suggestions may help you:

Your server is currently offline.
GameTracker needs your server to be online before you can add it to our database. Please restart your server and make sure it's up before hitting ADD SERVER again.
You entered the wrong query port.
Please update your query port and hit scan again
Your server is firewalled.
Please turn off any firewall you have that may block scanning or whitelist the gametracker scanning IP addresses:
208.167.241.190
208.167.241.185
208.167.241.186
208.167.241.183

The above message does not indicate that your IP is banned.
It is a list of items you must check to allow Gametracker to scan your server.
