SSL will not renew with external DNS

Project name: 4thgroovesiterebuild
Netlify subdomain: 4thgroovesiterebuild.netlify.app
Primary domain: www.4thgroovegodley.com
Alias: 4thgroovegodley.com

DNS is externally managed through GoDaddy:
A @ → 75.2.60.5
CNAME www → 4thgroovesiterebuild.netlify.app

Both domains serve the Netlify site over HTTPS, and both pass Let’s Encrypt HTTP-01 validation through Let’s Debug. However, Domain Management still says www.4thgroovegodley.com`` doesn't appear to be served by Netlify, and clicking Renew Certificate does not update the certificate timestamp or clear the warning.

An unused Netlify DNS zone was created during setup and has since been deleted. Please reset or repair the custom-domain/certificate association so automatic renewal works.
