Hi @mikegcoleman. Welcome to GoDaddy Community! A 404 error usually means that the browser can't find a default file or the file specified in the address bar. A "Page OK" error usually means that a domain is pointed toward the IP address for hosting plan that it hasn't been added to. I'm not sure what you'd need to do in your situation, but this information may help.
The primary domain for a cPanel account is always hosted in /public_html
If you add an addon domain or subdomain, they are typically hosted in /public_html/[domain]
You can see where an addon or subdomain are mapped to in your Addon Domains or Subdomains page in the cPanel dashboard. This information will be listed under "Document Root" on either of those pages.
I hope that helps. If not, you may consider connecting with our customer care team so they can take a look.
