Server not responding only to me

Server: Pub-Gamer.com: Trouble in Terrorist Town
Server IP: 118.127.19.59:27015

I seem to be the only one having this problem. Everyone is able to go into the server except me who can’t see the server in the servers list and get

Connecting to 118.127.19.59:27015…
Retrying 118.127.19.59:27015…
Retrying 118.127.19.59:27015…
Retrying 118.127.19.59:27015…
Connection failed after 4 retries.

when I connect from console.

I asked a admin friend of mine to check the IP ban list and ID ban list but he said that I’m not in there.

Any idea whats wrong? Need help thanks.
