cloudflare for saas cannot connect to 443

I'm following https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/start/getting-started/ to add custom hostname. The custom hostname work as the images shows. Which means fallback origin also works in prior to this. And I have added a CNAME of www.pagebrew.co to pagebrew.wolio.co This is what I get

curl -ii https://www.pagebrew.co/

HTTP/1.1 200 Connection established

curl: (35) error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

curl -ii https://www.pagebrew.co/

HTTP/1.1 200 Connection established

curl: (35) error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure

Is this normal? How can I resolve this?

Guess I have to @Chaika again here. I couldn't locate the original post where you recommend me to use cloudflare for saas to CNAME external domains. I got a weird response https://discord.com/channels/595317990191398933/1246401925910626334 I tried 2 domains for custom hostname 1. CNAME www.pagebrew.co(other registrar) => pagebrew.wolio.co ==> curl: (35) error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure 2. CNAME www.mrbird.dev(cloudflare) => mrbirddev.wolio.co ==> 522 error My setup
DNS for wolio.co AAAA * 100:: Proxied AAAA fallback 100:: Proxied Worker routes *.wolio.co/* ==> worker-router */* ==> worker-router
DNS for wolio.co AAAA * 100:: Proxied AAAA fallback 100:: Proxied Worker routes *.wolio.co/* ==> worker-router */* ==> worker-router
The guides I'm trying to follow but honestly I'm confused right now https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/start/advanced-settings/worker-as-origin https://github.com/berrysauce/cloudflare-saas-worker/tree/main https://community.cloudflare.com/t/522-error-when-accessing-worker-via-cname/558115 https://community.cloudflare.com/t/how-to-properly-set-up-a-custom-hostname-with-a-worker/329219
