TLS handshake fails on one Netlify edge (99.83.190.102) causing intermittent ERR_SSL_PROTOCOL_ERROR

Hi Netlify team,

I’m experiencing intermittent ERR_SSL_PROTOCOL_ERROR on my custom domain:

The issue appears to affect only one Netlify edge.

DNS:

75.2.60.5
99.83.190.102

Testing each edge individually:

Working:

curl -Iv --resolve vaid.store:443:75.2.60.5 https://vaid.store

Result:

  • Valid Let’s Encrypt certificate
  • HTTP/2 200 OK

Failing:

curl -Iv --resolve vaid.store:443:99.83.190.102 https://vaid.store

Result:

LibreSSL: error:1404B438:SSL routines:ST_CONNECT:tlsv1 alert internal error

SSL Labs also reports:

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

My DNS is configured correctly:

A 75.2.60.5
A 99.83.190.102
CNAME www → tanvishcouture.netlify.app

The domain is attached to Netlify and is marked as the primary domain.

Could someone please check the TLS/certificate configuration for the 99.83.190.102 edge or reprovision it?

Thank you.
