My server (surf.mnx. ro - 89.34.25.43:27015) was recently added on GameTracker and i can't see server banners on Gametracker. I encountered this error: "THE SERVER YOU REQUESTED IS NOT IN THE DATABASE GAMETRACKER."
Please help me to solve this problem. Thanks

I expect it may have something to do with your use of dns?

If you check using HLSW, there is no server currently running at IP:port 89.34.25.205:27015

However, it is listed here
http://www.gametracker.com/server_info/89.34.25.205:27015/

I do not understand, but I notice that my server is intercalated with "+19 FunnY.Laleagane.Ro +18" - 188.213.212.43:27015.

my server, surf.mnxro who has ip: 89.34.25.43:27015
https://www.gametracker.com/server_info/surf.mnx.ro:27015/

The DNS you enter is resolved when you put it in the URL. If the resulting server page does not exist, you get the message that the server cannot be found.

If you've recently pointed your DNS to a new IP, you may need to wait 24-48 hours for GT to be able to notice an IP change.
