This is very general - possible causes can cover many, many topics including DNS, Apache, Linux, firewalls and who knows what else. Let's try and narrow it down.
How do you access your server - local machine, ssh on LAN, remote ssh?
What's your server's ip address (it seems to be 220.127.116.11 but please confirm)? (using that ip your server seems to be totally unreachable from outside)
