www CNAME doesn't work - 522 error

I have configured CNAME for www to point cloudflare page but I get an error 522 when I am trying to open the page via www.genarabkin.com instead of https://genarabkin.com

did you add the cname in your dns settings or via your pages settings

Also if your www site doesn't differ from your root site then maybe just redirect from www to root?

Do you have both sites configured for your pages project?

Ok resolved guys. I found similar post with the page https://community.cloudflare.com/t/dns-cname-www-record-error-code-522/418069/2

I added the www in pages "Custom Domain" and it works now. Seems like it is not enough to add the CNAME in DNS it should be added directly through Pages interfaces otherwise it doesn't work

yes the problem is exactly in this

Correct: https://developers.cloudflare.com/pages/configuration/custom-domains/#add-a-custom-cname-record

To ensure a custom domain is added successfully, you must go through the Add a custom domain process described above. Manually adding a custom CNAME record pointing to your Cloudflare Pages site - without first associating the domain (or subdomains) in the Cloudflare Pages dashboard - will result in your domain failing to resolve at the CNAME record address, and display a 522 error.
