Folks,
I know there is a thread on this but I cannot find an solution to this issue:
I have followed the article to extend isa 2004 ssl port range:
 
http://www.isaserver.org/articles/2004tunnelportrange.html

and have succesfully added a new ssl port of 4443 however when I try to access the url i am now faced with the following error message in my browser:
 




Network Access Message: The page cannot be displayed







Technical Information (for Support personnel)
    Error Code: 504 Proxy Timeout. The connection timed out. For more information about this event, see ISA Server Help. (10060)
    IP Address: xx.xx.xx.xx
    Date: 6/4/2008 1:45:48 PM

    Source: proxy

I am using isa as a web proxy
