Error configuring Cloudflare Pages custom domain

Developers Cloudflare Pages
1

I set up a custom domain on Cloudflare Pages, but when I access the address, an ERR_SSL_VERSION_OR_CIPHER_MISMATCH error is returned.
The pages.dev address works, but the domain does not.

https://redelimpanome-parceiros-app.pages.dev
https://parceiro.redelimpanome.com.br

Custom domain is pending, go through: Debugging Pages · Cloudflare Pages docs

The request return this
curl: (35) error:0A000410:SSL routines::sslv3 alert handshake failure
Could this be a problem with the SSL where the domain is hosted?

You’re missing the CAA Records for Google CA, Pages will either use Let’s Encrypt or Google:

;; QUESTION SECTION:
;redelimpanome.com.br. IN CAA

;; ANSWER SECTION:
redelimpanome.com.br. 14400 IN CAA 0 issuewild “letsencrypt.org”
redelimpanome.com.br. 14400 IN CAA 0 issue “digicert.com”
redelimpanome.com.br. 14400 IN CAA 0 issue “letsencrypt.org”
redelimpanome.com.br. 14400 IN CAA 0 issue “comodoca.com”
redelimpanome.com.br. 14400 IN CAA 0 issuewild “digicert.com”
redelimpanome.com.br. 14400 IN CAA 0 issuewild “comodoca.com”
redelimpanome.com.br. 14400 IN CAA 0 issue “globalsign.com”
redelimpanome.com.br. 14400 IN CAA 0 issue “sectigo.com”
redelimpanome.com.br. 14400 IN CAA 0 issuewild “sectigo.com”
redelimpanome.com.br. 14400 IN CAA 0 issuewild “globalsign.com”

The ones you are missing:

example.com. 300 IN CAA 0 issue “pki.goog; cansignhttpexchanges=yes”
example.com. 300 IN CAA 0 issuewild “pki.goog; cansignhttpexchanges=yes”

Add them to your DNS of the domain you want to add the custom domain for, wait a bit for propagation, and try deleting/readding the Custom Domain
