I ended up creating redirect rule from www to root. Under rules>Redirect Rules See https://blog.cloudflare.com/dynamic-redirect-rules/

at the moment your redirection seems working, it could've been simply a matter of propagation time. Anyway, keep in mind that pointing a CNAME to another CNAME is discouraged by the official RFC, so pointing your www subdomain to stron.ml, while stron.ml is already a CNAME should be avoided:

Don't use CNAMEs in combination with RRs which point to other names like MX, CNAME, PTR and NS.
