server GUI get connection reset due to port 80 when accessing Agent Managment

Hi,

After installing DLP server 12.0

When i access the managment GUI using https:// i can see the managment server.

When i try to click on System -> Agents -> Management , i get error page : The connection was reset

I looked at the URL that i get when clicking on System -> Agents -> Management , the link is: "javascript:menuManager.check('http://:80/Altiris/DLPAgentmgmt');"

Why is the link redirect me to HTTP (port 80), when the server is configure to use HTTPS ? How can i resolve it ?

Thank in advance.
Guy
