If the DNS challenge is enabled, other challenges are disabled by default.Caddy pioneered a new technology we call On-Demand TLS, which obtains the certificate for a name during the first TLS handshake that requires it, rather than at config load. To make this possible, Caddy may ask for an email address if one is not already available. Caddy serves all sites over HTTPS by default. However, the DNS challenge requires configuration.

This means it will not block startup or slow down your sites. Is it possible?

The following is required whenever a Caddy server at x.x.x.x requests a cert for use on www.domain.com: www.domain.com resolves to x.x.x.x; x.x.x.x accepts connections on ports 80 and 443 You can enable it using the This feature can be useful if you do not know all the domain names up front, or if domain names you know of may not be properly configured right away (e.g. A site name qualifies for a wildcard if only its left-most domain label is a wildcard.
