I have created an “A Record” on my GoDaddy DNS console, e.g. xxx.yyyyyy.com
But when I need to add xxx.yyyyyy.com into my Netlify app, it says:
yyyyyy.com is already registered. If you registered this domain name through a different registrar, select Add domain to begin delegating it to Netlify.
But I added yyyyyy.com already, if I just typing xxx, it would say:
Invalid domain name
We couldn’t recognize your domain name. If you’re certain that it’s valid, please contact support for guidance.
It is always helpful if you can provide the domain in question rather than random placeholders.
If you are adding a subdomain to a site and using external DNS you need to create a CNAME record with that points to the Netlify site you wish to associate the domain with.
In this instance, you press the “Add domain” button.
If you have any issues, please provide the domain you are using, and the Netlify site you are wishing to connect the domain to.
In order to add app.promex.io, as per previously linked documentation, you need to create a CNAME pointing to your Netlify domain, and add it as a custom domain to said site.
