Access website from bought domain through https

Hi, this is my first time posting to this forum so im sorry if i am no writing this in the right section.
I currently have a website on altervista that uses the default domain "domain.altervista.org". I recently bought a new 2nd level domain like "mydomain.com".
Now i want my website to be accessed through that new domain and with https but i cannot get it to work. Can anyone guide me through this please? What more information do you need to help me?

What is the second level domain? It works?

If you want to "force" to use the second level domain, you have to set the .htaccess to do it. For example:

Code:

---

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.ygocollecting\.altervista\.org$
RewriteRule (.*) http://www\.ygocollecting\.com/$1 [R=301,L]

---

Bye!
