SSL Not working correct

Hi!
i have a site; tjoepie.erikplomp.nl
I mapped websitelight.nl
When i directly visit websitelight.nl 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 https://websitelight.nl it works, but the standard page from the theme is shown. So SSL and non-SSL are different.
I have let's encrypt with *.websitelight.nl and websitelight.nl setup. websitelight.nl is setup as an alias/domainpointer in erikplomp.nl in directadmin.
You can still acces my site with support granted i think. Please let me know. Regards Erik
