Custom domain intermittently fails with ERR_SSL_PROTOCOL_ERROR although DNS resolves point to Netlify

Hi Netlify Support,

I’m experiencing an SSL/TLS issue on my custom domain that intermittently fails with:

ERR_SSL_PROTOCOL_ERROR

Netlify site name:
zingy-cassata-95a9e5.netlify.app

Custom domains:

Current behavior:

  • Site sometimes works (for example on mobile hotspot)
  • Fails on home Wi-Fi and for multiple users
  • Browsers show “This site can’t provide a secure connection”
  • Netlify dashboard shows:
    wolf-motors.com doesn’t appear to be served by Netlify”
    and “Pending DNS verification”

DNS configuration (external DNS at Network Solutions):
A records for apex domain:
75.2.60.5
99.83.190.102

CNAME for www:
zingy-cassata-95a9e5.netlify.app

dig results from macOS terminal:

dig wolf-motors.com A +short
99.83.190.102
75.2.60.5

dig www.wolf-motors.com CNAME +short
zingy-cassata-95a9e5.netlify.app.

HTTPS / SSL/TLS:

  • Let’s Encrypt certificate exists
  • Netlify reports it cannot auto-renew because the domain “doesn’t appear to be served by Netlify”
  • No Cloudflare or other proxy/CDN is in front of the domain

Registrar/DNS provider:
Network Solutions

At this point DNS appears correct and resolves to Netlify, but TLS provisioning seems inconsistent across resolvers.

Could you please:

  • Verify the domain is fully recognized as being served by Netlify
  • Reset or reprovision the Let’s Encrypt certificate
  • Check for any inactive Netlify DNS zone or cached validation issue on your side

Thank you for your time and support. Happy to provide additional diagnostics if needed.

This is wrong. Please check out previous posts (there are several):

Hi Hrishikesh
The invalid A record (99.83.190.102) was removed, and the domain now points only to 75.2.60.5 DNS has propagated and SSL is working correctly across networks.
Thank you very much for your help
