Hello
I can not add a server to the monitoring, writes an error and more
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
208,167,241,189
108.61.78.147
108.61.78.148
108.61.78.149
108.61.78.150

Server clean, no no no AmxMod and metamod.

I can connect, but obavit it somewhere or not

I'd expect you need to open the port in your firewall, but don't have enough information to help.
