My cs 1.6 ReHLDS server is not scanning i can connect server in game but game tracker is not scanning how can i do this add server process?

Error:
GAMETRACKER COULD NOT SCAN THE SERVER.
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:
149.28.43.230
45.77.96.90
108.61.78.150
