Vercel subdomain nebwork.vercel.app unreachable despite valid configuration status

Help

Hi everyone,
I’m having an issue with my domain nebwork.vercel.app. It shows as “Valid Configuration” and “Production” in my dashboard, but it’s completely unreachable from any browser or device.

What I’ve tested

New project test

  1. Created a brand new Vercel project
  2. Added a new domain (ned-work.vercel.app) → works perfectly
  3. Assigned the problematic domain (nebwork.vercel.app) to the same new project → does NOT work

The issue seems specific to the domain name itself, not my project.

DNS resolution

nslookup nebwork.vercel.app 8.8.8.8

The domain resolves, so it exists in global DNS.

Preview URLs work

nebwork-f6fhmwp5m-explotador72s-projects.vercel.app resolves correctly and serves my project.

Online tool analysis

Using mxtoolbox.com/domain/vercel.app/, I found this warning:

Warning: SOA Serial Number Format is Invalid

This might indicate a configuration issue at the parent domain level.

What I’ve already tried

  • Domain shows as “Valid Configuration” in Settings → Domains
  • Removed and re-added the domain (waited 30+ minutes)
  • Flushed DNS, tested on multiple devices/networks

Questions

  1. Has anyone seen this with a .vercel.app subdomain?
  2. Could the SOA record issue be related?
  3. Is there a way to force a full domain revalidation?
