using cloudflare DNS ?

I can't add domain my-domain.qd.je to cloudflare. they tell me that is a sub-domain then can not be add. :(

Add qd.je to Cloudflare as the primary domain, not example.qd.je.
After that, Cloudflare will provide its nameservers, and you need to set them with the domain registrar for qd.je.
Within the qd.je zone, you can then create a record example:

• A → pointing to your server’s IP address, or
• CNAME → pointing to another host, if needed.

Some niche suffixes are not allowed to be added to cloudflare, but org and kg endings can be added to
