I am experiencing a persistent issue with my custom domain configuration. I hope you can help me resolve this once and for all.
Project Details:
Project name: Tu Canción
Vercel subdomain (working): tu-cancion.vercel.app
Custom domains (problematic): tucancion.app and www.tucancion.app
Current Status:
The subdomain tu-cancion.vercel.app works perfectly.
When visiting tucancion.app or www.tucancion.app, the browser shows:
This site can’t provide a secure connection
ERR_SSL_PROTOCOL_ERROR
DNS Configuration:
A record for root domain: 76.76.21.21
CNAME record for www: cname.vercel-dns.com
Attempts to Fix:
Cleared browser cache and cookies.
Tried different browsers and incognito mode.
Waited several hours for DNS propagation.
Verified DNS records multiple times.
Attempted to remove and re-add the domains in Vercel dashboard, but the UI shows: Failed to fetch.
Observations from Vercel:
The Vercel dashboard indicates DNS Change Recommended for both tucancion.app and www.tucancion.app.
SSL certificate is issued (Let’s Encrypt) and appears valid from the infrastructure side.
Dashboard is unable to manage the domain despite it being healthy from infrastructure perspective.
Request:
I need Vercel support to force-remove and reattach both domains from the backend, regenerating the SSL certificates to resolve this issue permanently.
Please advise or perform the backend operations needed to ensure that:
Both tucancion.app and www.tucancion.app work correctly with SSL.
No further manual intervention is required from my side.
The configuration will remain stable for production usage globally.
Thank you for your prompt assistance.
Hello Vercel Support Team,
The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points.
You can also use v0 to narrow down the possibilities.
The SSL certificates seem to be valid now and DNS has fully propagated, are you still seeing issues here? Sometimes it just takes some time to propagate globally
@vcgraphicdesign, I wanted to check in regarding the SSL issue with your custom domain. Are you still experiencing problems, or has everything resolved on your end? Let me know if that helps!
