The SHOUTcast administration page is not accessible with HTTP/SSL. This is a known issue with SHOUTcast 2.6 server and is not a problem exclusive to MediaCP software.
We have contact SHOUTcast support about this and have received the following response:

Hello,
Sorry to hear that.
https was never implemented for the admin pages.
It was only ever implemented for the index page and actual stream.
There would need to be a new DNAS release with added support.
Hope that will be useful!
Regards
