Yes! Its working now.
But I do have a concern, by doing it this way, doesn't that prohibit hosting a website with GoDaddy (or any other provider)? Since everything is pointing to @, which in turn points to my Unraid box.
Just for anyone else that is struggling with this (I did find the instructions somewhat unclear):
Setup your GoDaddy DNS like this (ncloud is the example here):
And then in the field "Domain Name" enter your primary domain, "yourdomain.com", not "@" or "ncloud" (in my case) as the instruction on the docker setup pages says.
