Summary: Our production tenant has disappeared and all our users are locked out. It is no longer in our tenant list in the dashboard, and the hostname now returns a 404. We need help recovering it urgently.
Tenant: referral-trail-production.eu.auth0.com (EU region)
Symptoms:
- Every endpoint on the tenant returns HTTP 404 with body “Unknown host: referral-trail-production.eu.auth0.com”, including
https://referral-trail-production.eu.auth0.com/.well-known/openid-configuration. - The tenant is no longer listed in our Auth0 dashboard tenant switcher.
- Our other tenant,
referral-trail-develop.eu.auth0.com, is completely unaffected (returns HTTP 200 on the same endpoint).
Impact: Full production outage — no user can log into our application, and our backend Management API calls against this tenant are also failing.
What we’ve already checked:
- DNS resolves correctly to Auth0’s edge, so the 404 is being returned by Auth0 itself.
- The develop tenant working while production is gone tells us this is isolated to the one tenant.
- Missing from the tenant list + serving a 404 suggests the tenant has been deleted (not merely suspended).
What we need help with:
- Can a deleted tenant be recovered, and is there a time window for this?
- What are the exact steps, and what does Auth0 need from us (verification, etc.) to restore it?
- Would the tenant’s users, connections, and application configuration be restored intact?
- Is there a way to confirm when and by which account it was deleted?

I can share our account/owner details privately with an Auth0 staff member — happy to DM. This is a live production outage affecting all our users, so any expedited guidance is hugely appreciated. Thank you.
