dns not resolving for sites after wildcard ssl install

I've been working through getting my multisite installation ready at https://fistbump.press. I got the sites working, and completed a successful registration of a test site. But then I upgraded my SSL through cPanel to a wildcard SSL. But now sites are not loading anything and getting DNS errors. I've been through everything I can find, but am not getting anything that is making a difference. Here's an example site:

http://bibledudelife.fistbump.press/

I can also go through the registration process successfully here, but then the site links end up not working due to the same DNS errors:

https://fistbump.press/wp-signup.php

Thoughts? Guidance? Thanks!
