Hello,
Iam logging through webdispatcher only not through any other link, after login in the pages for portal(User administration,system administration etc.....) is working now and then perfectly, but while clicking on backend links like ESS or MSS it will show the below screen.
This is occurring due to incorrect definitions at the system object related to the backend systems.
You should edit them and change them to use HTTPS protocol and to go through the Web Dispatcher HTTPS port.
The following WIKI page might help you.
Regards,
Isaías
