You should look at the Shoutcast DNA's first, for more information.
So if your stream is at (for example):
http://sc3.shoutcaststreaming.us:80001- Is the server status reported as CURRENTLY UP AND PUBLIC ? If so, post the link and we will take a look.
If not, then click on the Admin Login, on the top right.
Log in:
user: admin
password: ********
Click on Tail Logfile ... look to see if there are any errors to the YP in shoutcast, or in general.
