Double-check and make sure to switch the proxied to unproxied (DNS-only).
You’ll have to ask whoever is hosting that target for clarification as you’re using a CNAME records that points to a Cloudflare account already, which as 1014 error explains is not allowed to host external CNAMEs.
Seems like you’re using some 3rd-party service which is on Cloudflare.
currently i redirect from kelas.baleomol.com to kelas.orderan.me.
it’s already proxied only.
i give a cloudflare config from the target (dns.uteach.io).
my dns was blocked, and they don’t know why my dns is blocked
