Www.mydomain.com works, naked mydomain.com does not

All other threads I’ve found via search either reference links that 404 or tell me to add Page Rules that do not work anymore. My setup is:

A chrissardegna.com ip_address proxied
CNAME www chrissardegna.com proxied

and two other CNAME records for mail and ftp.

This worked previously and something changed without having Page Rules, so I know that page rules are not the answer.
