Alter failed? Cloudflare

I want to use cloudflare from the cpanel to add a dns record. I tried to alter it then it’s say user_key not found etc. Tq

Are you using a free subdomain or a regular domain? If you’re using a free subdomain, Cloudflare is not supported on those yet unfortunately.

Also, I would like to point out that if you’re going to enable Cloudflare from our control panel, you will not be able to set custom DNS records in Cloudflare. If you want to have that level of control, you’ll probably want to add your domain to Cloudflare yourself.
