Help! CNAME record is not updated

CNAME(www) won’t apply new info, it keeps old info. (Proxied, Auto TTL) - changed more than 24 hours ago.
if I set it to DNS Only, then it works. However, I cannot set to ‘DNS only’ because I need the proxy on because I need Cloudflare SSL certificate.

Any help?

You need a certificate on your server anyhow, otherwise they site cannot be secure.
