New WordPress Mulitsite - Subdomains not working

I just set up the multisite yesterday. I edited the wp-config and the .htaccess as directed and set up wildcard subdomains.

I created a couple new sites in the network admin area, everything with WordPress worked perfectly, got the emails with logins etc.

When I try to visit the sites it just takes me to a screen that says "This site can't be reached’s server IP address could not be found."

What am I doing wrong? how to I make the sites available? I'll go ahead and enable support access if you want to take a look.
