DNS unable to resolve Lightsail Wordpress site

I was having some issues with setting up the DNS on my new Lightsail site and I asked a question here.

The site seemed to be working after I added a CNAME, but a few hours later on I tried to access the URL and DNS can't find my site. If I try my static IP address, it resolves to http://www.supersurvivalsupply.com/wp-signup.php?new=3.22.196.179.nip.io With this error message: "www.supersurvivalsupply.com’s server IP address could not be found."

So any help would be nice.
