NetFlow Analyzer and SSL setup

Hi,

I downloaded this application and I followed your instructions on this link:
https://forums.manageengine.com/topic/how-to-enable-ssl-in-netflow-analyzer-professional-edition

to enable SSL in NetFlow Analyzer. I also have the server configured with SSL working and tested. I tried to set it up on two different machines :

Windows 2003 IIS 6 with https setup and tested

CentOS 5.5 , Apache 2.2.3 with SSL configured and tested.

I can connect to Netflow Analyzer via http://ipaddress:8443 but cannot connect securely to https://ipaddress:8443 It just gives the following error :

The connection was interrupted

The connection to w-netflow-v.wreal.mia:8443 was interrupted while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection.

If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

If I modify ssl.conf to listen on 8443, then when I start Netflow Analyzer it complains that the port is already taken.

What else can I do? Please, help.
