Most likely it's because you're using a non-SSL resource on an SSL page. On your SSL page, try replacing:
<script language="javascript" type="text/javascript" src="http://stream.shellservers.net:2199/system/streaminfo.js"></script>
with:
<script language="javascript" type="text/javascript" src="https://stream.shellservers.net:2199/system/streaminfo.js"></script>
Not sure why the browser isn't throwing a warning about that (I'm sure you've seen the ubiquitous "This page includes content that is not secure, bla bla bla" warning on other sites before), but that's the most likely reason it isn't working.
