The mentioned domain,
g8mails.com, is currently having the status clientHold, which literally means that the domain is suspended.
clientHold is often used when there are problems, such as e.g. legal disputes, or lack of payment.
clientHold is also sometimes set by some domain registrars, when the client fails to validate their domain contacts (e.g. the registrant email).
I will advice you to create a registrar ticket. Visit https://dash.cloudflare.com/?to=/:account/support and choose “Cloudflare Registrar”.
Once you have created a ticket, please share the ticket number.
