Is your server publicly exposed on the internet? It's mandatory for Caddy to generate the TLS certificate using Let's Encrypt.

No i just work locally to upgrade my skills, i search to use another host to my actual caddy server
To use "monsite.com" instead of "monsite.localhost"

I can make that with nginx or apache, but i can't do it with caddy

Actually caddy give this followings url => https://monsite.localhost/

Ok i solve my problem with this followings instruction

I change my SERVER_NAME env var in my .env.local file to monsite.com into http://monsite.com, to "disabling" ssl and its work !

I find auto_https disable_redirects but its available only from v2.1 of caddy

Thanks for your help, i close this issue

Alternatively, you can use a self-signed TLS certificate: https://caddyserver.com/docs/caddyfile/directives/tls

To generate a valid certificate for a real domain, Caddy must be exposed publicly on the internet.

Hello, does this means that starting the container on a produciton server will not be enough ? What do you mean by " exposed publicly " ?
