Vercel custom domain shows invalid configuration after updating DNS records

Help

Description:
After Vercel updated their DNS records, my previously working custom domain stopped functioning. The domain was correctly linked to my Vercel project before the update, but now the Vercel dashboard shows an “Invalid Configuration” warning.

Steps to Reproduce:

  1. Configure a custom domain with Vercel (previously working setup).
  2. Allow DNS propagation and confirm domain resolves correctly.
  3. After Vercel’s DNS record update, check domain status in the dashboard.
  4. Vercel reports Invalid Configuration and fails to issue an SSL certificate.

Expected Behavior:
The domain should remain correctly linked, pass configuration checks, and receive a valid SSL certificate.

Actual Behavior:

  • Vercel dashboard shows Invalid Configuration.
  • SSL certificate is not issued.
  • Running all Vercel-provided DNS test tools confirms the domain is correctly configured.
  • Domain does not link to the app despite correct DNS setup.

Additional Context:

  • Screenshot attached showing the Invalid Configuration message.
  • DNS records match Vercel’s documentation and pass external verification tools.
  • This issue started only after Vercel updated their DNS records.

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.

Hi @zelalemgta, welcome to the Vercel Community!

I’m sorry that you’re facing this issue.

I can see the DNS propagation has finished for this domain. It seems like a transient issue the domain got stuck in. Could you remove and add back the domain? This should solve the issue.

Thanks @anshumanb for the support. Unfortunately, I tried removing and re-adding the domain but it still didn’t work.
