User manager and SSL certificate

Hi

I got on my Lan ( hotspot ) side domain that works with certificate that users access with url: https://mydomain.com. This is a secure login page, OK?


Then
Once user logged in and wants to see the user page, he/s has to enter the following url:
http://mydomain.com:808/user.


My question is:
How come when a user tries to access the user page with secured connection that is url:
https://mydomain.com:808/user gets message:

This webpage is not available!


And with url:
http://mydoamin.com:808/user gets finally the user page but NOT secured.


I want to have secure connection to user page. for my cliebts/users


I user the same domain name for both, that is mydomain.com on hotspot ( DNS name) ( local LAN ) 192.168.1.1 and on WAN ( 77.9.78.xx.x ) side of the MT Router board connections.

Should i get SSL certificate that supports sub domains? that would solve the problem . Other ways user has UNSECURED connection for user manager. Looks like Userman runs on WAN not on LAN ( hotspot )

With: https://mydomain.com/user get:

Err: Error 404: Not Found


How to tell the Hotspot WWW service to got and grab/redirect user to WAN IP where usermanager is runing when they are logged in and typed https://mydomain.com/userman or /user?

Hmmmm?
