HTTPS in sub domain redirects to main domain [closed]

Question

We recently bought a wildcard certificate and installed it for a domain. It works fine for the main domain but seems to not work at all for any sub domains.

Whats happening is we can access the sub domains fine on HTTP, but whenever we try HTTPS for the same sub domain url we are redirected back to the main domain.

So if I put up a test folder httpstest in a sub domain with an index.html file in it, the following happens:

• mysubdomain.mywebsite.com/httpstest/index.html or

• mysubdomain.mywebsite.com/httpstest/

works perfectly fine with HTTP, but

• mysubdomain.mywebsite.com/httpstest/ or

• mysubdomain.mywebsite.com/httpstest/index.html

does not work with HTTPS and redirects to the main domain [mywebsite.com].

The site is not the main site used for setting up the VPS. It was added from WHM.

Environment: We are on a Linux VPS.
Cpanel 11.30.6 , Apache 2.2.22, PHP 5.3.13

The Virtualhost entry looks like this:

<VirtualHost xx.xx.xxx.xx:443>  
    ServerName my-own-website.com    
    ServerAlias www.my-own-website.com  
    DocumentRoot /home/amitabh/public_html

    # To customize this VirtualHost use an include file at the following location  
    # Include "/usr/local/apache/conf/userdata/ssl/2/amitabh/my-own-website.com/*.conf"  

</VirtualHost>

I posted the same question in a linux forum.
