Domain mapping simply isn't working as needed

Alright… Domain mapping. It’s set up as correctly as I know how, and it will not validate a domain I know is pointing at my dedicated incoming IP address. Wildcards work well, the domain’s DNS has been pointing at the IP for over a day (even received the standard notification email from GoDaddy already)

What do I have to do to get it working? Totally willing to open up the domain for support (already turned it on)

Thanks in advance for your time guys and gals.
