SSL Not working correct

i have a site;
I mapped
When i directly visit it is http, and shows the page like it should. A landingpage from thrivethemes is shown.
But it should be forced to SSL.
When i visit it works, but the standard page from the theme is shown. So SSL and non-SSL are different.
I have let's encrypt with * and setup. is setup as an alias/domainpointer in in directadmin.
You can still acces my site with support granted i think. Please let me know. Regards Erik
