Subdomain not working with ip vps v4

#1

My subdomain is created on cpanel with no redirecte. and I use it on cloudflare to redirect to ip v4 of vps but it reports a Host error. subdomain–> ip vps v4. cname a ->> subdomain.

#2

I have an IPv4-only machine in my Cloudflare account and its subdomains are working. They don’t use cPanel, but that shouldn’t matter. I only have “A” records, and no “AAAA” records.

If you could post the URL of what’s not working, that would help. Maybe even some screenshots of DNS (OK to redact IP addresses) and Page Rule(s).
