Custom domain shows ERR_SSL_PROTOCOL_ERROR despite correct DNS and valid SSL (Apex + www)

I’m experiencing an issue with a custom domain that appears correctly configured but is not serving over HTTPS.

:link: Domain

  • juagrid.africa

  • www.juagrid.africa

:globe_with_meridians: Netlify Site

  • roaring-starburst-bd5d26.netlify.app

:white_check_mark: What’s working

  • DNS is correctly configured at OnlyDomains:
@     A      75.2.60.5
@     A      99.83.190.102
www   CNAME  roaring-starburst-bd5d26.netlify.app

  • nslookup juagrid.africa resolves correctly to:

    • 75.2.60.5

    • 99.83.190.102

  • SSL certificate is issued (Let’s Encrypt) for:

    • juagrid.africa

    • www.juagrid.africa

  • Project deployed is a simple static HTML site (no frameworks, no custom headers, minimal _redirects)

:cross_mark: Issue

Both domains fail to load:

  • https://juagrid.africa

  • https://www.juagrid.africa

Error:

ERR_SSL_PROTOCOL_ERROR

:magnifying_glass_tilted_left: Additional observations

  • Netlify initially showed:

    • “juagrid.africa doesn’t appear to be served by Netlify”

  • After reattaching domain and redeploying, SSL shows as issued, but site still fails

  • At one point, site worked briefly, then broke after SSL renewal attempt

:wrench: What I’ve already tried

  • Removed and re-added custom domains

  • Created a fresh Netlify site and redeployed clean ZIP

  • Verified no redirect loops or forced HTTPS in code

  • Tested with minimal index.html only (no config files)

  • Confirmed no AAAA records, no forwarding, no Wix involvement

  • DNS propagation confirmed globally

:red_question_mark: Question

Could this be:

  • a stuck edge binding issue?

  • SSL validation mismatch between apex and www?

  • or something requiring backend reset on Netlify side?

:folded_hands: Request

Could you please:

  • check if the domain is correctly attached at the edge

  • confirm if SSL is properly bound to both apex and www

  • advise if a manual reset is required
