Custom Domain Github Pages

So I've followed the directions for setting up a custom domain with Github Pages. As per their recommendation, I'm attempting to set this up using a custom subdomain.

I purchased my domain through GoDaddy, and using their DNS Manager tool I added myappname.github.io under Host (CNAME):

I didn't change anything else, such as that IP address under A (Host).

Lastly, on my Github page when I go under settings it correctly says "Your site is published under www.myappname.com"

Yet, when I go to www.myappname.com, I see the following:

enter image description here

What did I do wrong?

Edit:

Output from dig:

dig www.myappname.co

Your DNS is configured to redirect the www subdomain to your GitHub Pages site, but your GitHub Pages CNAME file specifies that your application should run on the apex domain, myappname.com. This causes another redirection to the apex domain, which as you point out in your question has its own A record pointing to a non-GitHub IP address.

As we discussed, one possible solution is to update the CNAME file in your repository to use www.myappname.com instead of myappname.com and then set up a redirect from the apex domain to the www subdomain.

This will cause requests to myappname.github.io and myappname.com to redirect to www.myappname.com, where your site lives.
