Custom Domain (why-doc.com) not working even after 4 days

Help
1

Current:
I connected the domain why-doc.com via Gabia and set both A and CNAME records as documented, but the site still shows DNS_PROBE_FINISHED_NXDOMAIN. It has not resolved even after 4+ days.

Expected:
The custom domain should resolve to my deployed site on Vercel without any DNS error.

  1. Domain why-doc.com purchased via Gabia
  2. Set A Record: @ → 76.76.21.21
  3. Set CNAME: www → cname.vercel-dns.com.
  4. Set nameservers:
  • ns1.vercel-dns.com
  • ns2.vercel-dns.com
  1. Assigned domain to Vercel project → Status: “Ready”, but DNS never resolves.

Also confirmed using intoDNS that nameservers are registered at the parent, but records aren’t returned properly by the Vercel nameservers.

  • Vercel Project: 123’s projects
  • Domain: why-doc.com
  • Deployment URL: https://why-doc.vercel.app (Working fine)
  • Framework: HTML/CSS (Static page for now)
  • Vercel Plan: Hobby
  • Environment: Production
  • Attached Screenshots:
    • Gabia DNS settings
    • Domain registration proof (with nameservers)
    • intoDNS report with NS record mismatch errors

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.

Just following up — it’s been over 4 days, and the domain why-doc.com is still unresolved.
I’ve double-checked the nameservers, and even intodns.com reports NS record mismatch errors.
Screenshots and documentation are already attached above.
Would appreciate further help on whether it’s a propagation issue or a nameserver config issue on Vercel’s side.
Thank you!

Hi @pretty42213-navercom, welcome to the Vercel Community!

From DNS Checker - DNS Check Propagation Tool I see that the DNS records are not set correctly. I’d recommend following the steps listed in the Project settings > Domains section of your Vercel dashboard.

Hi @anshumanb, thanks for the reply.

I have already double-checked all DNS configurations and followed every instruction in the Vercel documentation.

Here’s a quick summary again:

However, https://why-doc.com still shows DNS_PROBE_FINISHED_NXDOMAIN.

I also verified with IntoDNS and DNSChecker — nameservers are registered at the parent level, but no records are returned from the Vercel nameservers.

It seems like a propagation issue or a caching/misconfiguration on the Vercel side.
Could you help escalate or refresh the domain state on your end?

Thank you so much!

Hi @pretty42213-navercom, you only need to do one of the two: either follow the NS setup or the A/CNAME records setup.

So, let’s start fresh:

  • Remove the NS, A, and CNAME records from Gabia
  • Remove the domain from the project
  • Refresh the Vercel dashboard
  • Add the domain to the project
  • Now add the A record to Gabia
  • Add the CNAME record to Gabia

Wait for the DNS propagation. Let me know if this works.
