need help in running shoutcast

[Sadegh]

Hi,
I've installed Nginx on my ubuntu server with many server blocks.
Then I installed Shoutcast.
Now I run Shoutcast with this command:
./sc_serv &
it will run without error.
but when I open this address :
HTTP://myserveripaddress:8000
it shows this page:
The connection has timed out
Please tell me what I should do to solve this problem.
Thanks
