I figured this out on my end. Godaddy is my host as well. I noticed that when I typed in my domain name the www was removed when the page was loaded. I then noticed that my connection info from Printful contained www in the URL. I removed the www on the Printful side and it has been working ever since. What is suggest is that you enter your domain name in a browser and whatever that comes back as you match in Printful.
