Wildcard Automatic SSL Certificates

Help
1

As far as I’m aware, as of 0.9 Caddy does support wildcard subdomains for SSL + virtual hosts.

Currently, I’ve added:

mysite.com, *.mysite.com {
  ...
}

But the logs only indicate a challange for the mysite.com address, and instead chose to host *.mysite.com on port http://*.mysite.com:2015. Is there something special to support wildcard SSL certificates or did I misread this as a new feature of 0.9?

Thanks!

Seems I missed the part about max_certs, added that and it worked great!

Bingo - since Let’s Encrypt doesn’t issue wildcard certificates (yet, hopefully?), if you don’t know the hostname when you start the server you need to use On-Demand TLS to obtain certificates at request-time.
