Unable to verify secondary domain

Problem

When trying to verify the secondary domain, after 72 hours of adding the TXT verification record. You keep getting the following error message: 
We're currently unable to verify your domain. You might need to wait longer for your domain host to update your information. If that doesn't happen soon, try verifying again.

Environment

  • Admin console
  • Domain Management

Solution

  1. Check if you have used the domain as a domain alias in another Google Workspace account.
  2. Login to the Admin console.
  3. Go to Account > Domains > Manage domains.
  4. Find and click the Remove option beside the domain alias.
  5. Add the domain.
  6. Go to Account > Domains > Manage domains.
  7. Click Add a domain.
  8. Type the domain name in the domain name field.
  9. Select Secondary domain.
  10. Click Add domain & Start verification.

Cause

The domain is currently being used as a secondary domain or domain alias in another account. The domain was not verified on that account, so it allowed you to add it to your current Google Workspace account.
