The issue about changing the port number when SSL is require

Hi all,

I developed a Sitefinity 4.2 project and deployed it to the production site.  The production site requires the SSL and a different Port Number.  I checked the "Require SSL" property to every Sitefinity page in my project.  These pages on the production site can be accessed without problems.  But when I try to log in the Sitefinity as the Admin and after I enter the username and password and hit the "Login" button, I got the "Internet Explorer cannot display the webpage" page.  It looks like I logged in successfully, but somehow the main page in Sitefinity doesn't show up.  Could you help me with this problem?  I think the problem comes from the different port number.  How do I set the prot number in the Sitefinity?  Thank you for help.
