DNS Error

I have our root domain managed and hosted on vercel. I'd like to configure a subdomain of this domain to be hosted by cloudflare. I set the CName as suggested (Name: <my-subdomain) Target: <my-pages-name>.pages.dev) in my Vercel's DNS settings When I go to "Custom domains" settings in my pages project, it shows the subdomain but says Inactive (Error) and when I go to the URL I see:
This site can’t provide a secure <my subdomain>.<my domain>.app uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
This site can’t provide a secure <my subdomain>.<my domain>.app uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Do I need to do anything else to configure it?

Means CF has no Certificate to use for SSL for this domain Inactive (Error) means it failed on the certificate part. Could be missing CAA records or some other blocking: https://developers.cloudflare.com/pages/configuration/debugging-pages/#missing-caa-records, could check if you provided the domain name
