Unrecognized directive: tsl

1. The problem I’m having:

New to caddy and trying to figure out how it works, apologizes in advance for mistakes.

I’m trying to use caddy on a network not connected to the internet.

My eventual goal is simply to create a proxy: forward (back and forth) all traffic reaching one machine to another machine which is not connected to any network other than via the previous machine. This should happen depending on name: name1.example.com should go to the other machine, name2.example.com should stay local. Hopefully, do that for any port automatically (if not possible, I guess I can specify each port as a separate entry).

To start learning I’m just following the tutorial (so serving dummy sites for now). and so Caddy is not working because it wants to use Let’s Encrypt. Following guidance on

Use Caddy without Let's Encrypt?

I am trying to run Caddy without internet access so I would like to disable Let’s Encrypt support. If my Caddyfile specifies localhost or an IP address Caddy seems to serve pages fine without using Let’s Encrypt. If I specify a hostname’s FQDN then it errors out. The error is, "error creating client: get directory at ‘https://acme-v01.api.letsencrypt.org/directory’: failed to get … x509: certificate has expired or is not yet valid How do I disable Let’s Encrypt so I can use Caddy without inte…

I added tsl things (either off or internal) and it doesn’t work

4. How I installed and ran Caddy:

a. System environment:

RH 9.6

b. Command:

dnf install caddy
systemct start caddy

d. My complete Caddy config:

http://localhost {
        respond "Hello world"
}

https://localhost {
#       tsl internal
        tsl off
        respond "Hello https world"
}

Welcome to the Caddy club

Just a couple of notes:

1. That’s a very old document you’re referencing.
2. There’s a small typo in your config. It should be tls, not tsl.

HTTP only:

{
    auto_https off
}

http://localhost {
    respond "Hello HTTP world"
}

HTTPS with HTTP-to-HTTPS redirect and internal certificate

localhost {
    tls internal
    respond "Hello HTTPS world"
}

Separate HTTP and HTTPS with internal certificate:

{
    auto_https disable_redirects
}

http://localhost {
    respond "Hello HTTP world"
}

https://localhost {
    tls internal
    respond "Hello HTTPS world"
}
