Troubleshooting secondary nameservers

When updating your registrar with the Cloudflare secondary nameservers (nsXXXX.secondary.cloudflare.com), you get an error.

Upon contacting your registrar, their services confirm that the Cloudflare nameservers cannot be added at this time.

​​ Root Cause

This issue may arise when one of our nameservers used for secondary setup are removed from the Verisign side.

​​ Solution

The Cloudflare engineering team needs to be engaged through Support to make sure the nameserver gets registered again manually at Verisign.
