Custom domain verification stuck on "verification record was not found" despite correct DNS (Early Access)

I’m trying to verify a custom domain and it never succeeds, even though the DNS is provably correct.

What I did

  • Created custom domain login.xxxxx.com (also tried auth.xxxxx.com earlier).
  • Added the exact CNAME Auth0 shows, DNS-only / unproxied, in Cloudflare: login.xxxxx.com CNAME dev-i4xu....5.edge.tenants.us.auth0.com

DNS verification (all correct)

  • Cloudflare authoritative NS (chip.ns.cloudflare.com), 1.1.1.1, and 8.8.8.8 all return the expected CNAME.
  • dig login.xxxxx.com CNAME +short returns dev-i4xu....5.edge.tenants.us.auth0.com.
  • The record is DNS-only (not proxied).

Problem
Clicking Verify always returns “The verification record was not found. You might need to wait a few minutes before we can discover it.” - including immediately on a brand-new subdomain whose DNS was already live and globally propagated before the first Verify click. A previous subdomain stayed in this state for many hours.

Since the DNS is correct and even a brand-new name fails the same way, this looks like a verifier-side issue on the Early Access Custom Domains feature for this tenant.

Could someone investigate? Thank you.

Hi @dralbertorodriguezhn

Can you please provide me through a DM the custom domain you are trying to use in order to investigate things from my end?

Kind Regards,
Nik
