About 'Non-existent domain'

Hi

I purchased the domain from AWS Route 53 and registered with the AWS Name Server.

8.8.8.8 resolves my sub domain well, but 1.1.1.1 does not.

Please understand that I can’t tell you my domain due to security issues.

Please help!
Thanks

It looks like your domain name has special characters, but without knowing the actual domain name, we can’t help.
