404 Issue With Pointed Domain

My Homestead website is xtremeleads.  When I first launched, I pointed domain, www.myxtremeleads.com to it.  This morning, I pointed a different domain to this website, www.xtrememobilemarketing.com.  Now, I get this message when trying to go to it. And when you go to "Homepage" it just sits and spins as that is the domain www.xtrememobilemarketing.com.  Please advise.  Thanks!!
