Www domain stuck on Pending DNS Verification despite correct cname

My primary domain is working correctly on Netlify, but the www version has remained stuck on “Pending DNS verification.”

My DNS is managed through GoDaddy.

The relevant DNS records are:

A record:

@ → 75.2.60.5

CNAME:

www → relaxed-genie-80d56d.netlify.app

The primary domain is:

derbycitymineralgallery.com

The www domain is:

www.derbycitymineralgallery.com

I checked the www CNAME from Terminal using:

dig www.derbycitymineralgallery.com cname

It returns:

www.derbycitymineralgallery.com. CNAME relaxed-genie-80d56d.netlify.app.

So the www CNAME appears to be resolving publicly to the correct Netlify site.

However, when I test the www address over HTTP, the response is:

server: nginx

rather than Netlify, and Netlify continues to show the www domain as “Pending DNS verification.”

The root domain is working correctly on the same Netlify project.

Could someone please help determine why Netlify is not verifying the www domain even though the CNAME is resolving correctly, and what I need to change to get www working and covered by the Netlify SSL certificate?

Thank you!
