WebsiteBuilder SSL

Why, when I try to work with the software WebsiteBuilder SSL, when activating my domain termovisionpuls.com,

the inscription Domain cant be verified as it doesn't exist on builder appears?AND MY SITE http://www.termovisionpuls.com is

published and hosted by homestead!

Can I create a new website with my existing 
termovisionpuls.com domain in my account application
