Seems like I can’t Register to .tk on cloudflare as it does help my server to point proper as I have one working fine on cloudflare but seems like new ones are not functioning proper if anyone has a idea of fixing it please tell me
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.
