HTTPS not available on GitHub Pages despite correct DNS and CAA configuration

Body

Hi, I'm experiencing an issue with HTTPS on GitHub Pages for my custom domain.

My site is hosted at www.finanzapmi.it, and DNS records have been correctly configured:

CNAME for www pointing to alessandromamone8-oss.github.io

CAA record added:

Tag: issue

Value: letsencrypt.org

Flags: 0

Despite this, GitHub Pages still shows the message:

"Enforce HTTPS — Unavailable for your site because your domain is not properly configured to support HTTPS."

I’ve already:

Verified DNS propagation

Cleared browser cache

Removed and re-added the custom domain in repository settings

Waited over an hour for certificate provisioning

Is there anything else I should check or reset to enable HTTPS?

Thanks in advance for your support!
