AppManager - URL Access

AppManager - URL Access

I have installed AppManager onto a Windows 2008 server, and can open the web console directly from the server.
 
However I am unable to open the web console, directly from my desktop via my URL: http://pd-vm-ssi:9090
 
Error message:

"Internet Explorer cannot display the webpage"

 
Are there any settings to enable remote access? Anything obvious to check?
 
Many thanks.
