Did you just add your domain name to your account? And did you use CNAME verification to add it? Then note that CNAME verification only proves that your own the domain name, it doesn’t actually make your domain name use our hosting. That’s why changing the nameservers is our recommended option: it does both at once.
The easiest way to fix this is to update your domain’s nameservers to point to our hosting anyway. Please see this guide for more information:
And for the specific instructions at Go Daddy:
If you prefer to use Go Daddy’s nameservers for any reason, you can do so too, provided that you configure the right DNS records in their nameservers. But do know that this is an advanced option, that should only be used if you understand how DNS records work.
