I have a caddyfile with a subdomain like “my.domain.com” it should be running with (auto-)TLS.
It is served HTTP only.
If I add prefix schema “https://” it works fine with auto TLS + LE cert.
Why I have to add schema? caddy is started with -port 80 and can bind to 80 and 443. That works fine if I add https:// scheme. So it looks like a caddyfile / caddy problem?
I think -port 80 is needed because the default port is 2015 instead of 80 (http)? Caddy should listen to 80 and 443 because it’s used as reverse proxy.
I’ll test it soon, because I’m away at the moment.
