No me deja añadir un sitio web

Al momento de añadir un sitio web en<>/add-site
me sale que “Failed to lookup registrar and hosting information of “mi dominio” at this time. Please contact Cloudflare Support or try again later.” antes me servia y ahora no, mi dominio termina en .cf, alguien que me ayude por favor. gracias.

That domain is registered under a TLD which is governed by the Freenom registry. Freenom currently experiences issues with their Whois service which prevents such domains from being added to Cloudflare. Freenom needs to fix that on their side. Unfortunately there is no ETA known for that.

It probably is best to register a proper domain instead. They already go for less than $10 a year.

What happens is that it had worked for me before, and the site had been added correctly, but as now I try to add it now and it won’t let me, because I don’t know what to do.
