My custom domain is configured on Vercel with “Valid Configuration” shown on both the domain and the project. The Vercel CDN shows as Active and the nameservers are set to:
ns1.vercel-dns.com
ns2.vercel-dns.com
However, the browser returns:
Error: ERR_NAME_NOT_RESOLVED
The .vercel.app deployment URL works fine.
What I’ve Tried
Reassigned the domain to the project multiple times
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.
