www..com not working, but .com is

Hi, I have my CNAME DNS entries set up like this:

CNAME mywebsite.com mywebsite-com.pages.dev Proxied Auto
CNAME www mywebsite-com.pages.dev Proxied Auto

When I type mywebsite.com in the address bar, it works

but if I type www.mywebsite.com in the address bar, I get a 522 error.

I updated the DNS entires 8+ hours ago.

Any idea what I'm doing wrong?

Thank you!
