Why is the Apple Touch Icon loaded via HTTP instead of HTTPS?

[Graphiwiz]

Your symptoms are implying that firefox is being case sensitive where Chrome is not. If you add a WWW version to the let’s encrypt domain list does that make Firefox happy?

I’ve added -d WWW.community.example.com but https://www.community.example.com still doesn’t redirect in FF.

This is what I get in FF:

SSL_ERROR_BAD_CERT_DOMAIN

www.community.example.com uses an invalid security certificate.

The certificate is only valid for community.example.com.

Unable to communicate securely with peer: requested domain name does not match the server’s certificate.

HTTP Strict Transport Security: false HTTP Public Key Pinning: false
