Domain config page says its using Netlify DNS but unable to renew certs

We’re not able to access our website “sirmesasit.netlify.app” on the custom domain “sirmesas.it” due to the following error

Your connection isn't private
Attackers might be trying to steal your information from sirmesas.it (for example, passwords, messages, or credit cards).
NET::ERR_CERT_COMMON_NAME_INVALID

The domain management page says both “www.sirmesas.it” and “sirmesas.it” are using Netlify DNS


yet when I try renewing the certificates I get this error

sirmesas.it doesn't appear to be served by Netlify

We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved. Check our troubleshooting guide for more information on how to fix the problem, and then renew the certificate.

Any Idea on what could be misconfigured?
Thanks in advance

Your DNS is incorrect:

dig CNAME +short @8.8.8.8 www.sirmesas.it
sirmesas.it.

dig A +short @8.8.8.8 sirmesas.it
213.144.92.116
75.2.60.5

The extra A record should go and the CNAME should point to your Netlify subdomain.
