Intermittent ERR_SSL_PROTOCOL_ERROR on custom domain despite valid DNS and certificate

My domain pujaricoexports.com has been connected to Netlify for over 5 days.

DNS records are:

A @ → 75.2.60.5

A @ → 99.83.190.102

CNAME www → fantastic-zuccutto-67f5bb.netlify.app

Netlify shows:

However, the site intermittently returns ERR_SSL_PROTOCOL_ERROR on different devices and networks.

SSL Labs shows:

  • 75.2.60.5 → A+
  • 99.83.190.102 → Failed to communicate with the secure server

Clicking Renew certificate reports:

DNS verification failed - pujaricoexports.com doesn’t appear to be served by Netlify
