Map domain issues (http(s))

I'm having issues with the "Map Domain" option.

Before adding anything it was working perfectly. After addig the domain, I realized it automatilly uses the http(s).

The problem is that the http (as we usually use) works perfectly, but when it comes to the http(s), there is a certificate error with the browser (firefox in this case).

Can this be solved? It would just need to change the http(s) for the http, but there is no such an option in configuration.

Thanks for your help.
