3CX "Invalid certificate key"

As of v20, the 3CX web config doesn't accept EC certificates (probably a bad regex in the webui - doesn't seem to actually send the request).

You must use RSA certificates

Caddy RSA, DNS-only Certificates

{
    auto_https disable_redirects
    http_port 61080
    https_port 61443
    default_bind 127.0.0.1
}

example.com {
    tls {
        dns lego_deprecated dnsimple
        key_type rsa4096
    }
}

I believe there is a way to limit caddy to certificate renewal only - and not bind to listen on any ports - but I don't know how yet.

Do have any prompt that will work on the new Duckduckgo chat?
