Disable auto HTTPS redirection using Caddyfile

1. Caddy version (caddy version):

v2.4.3 h1:Y1FaV2N4WO3rBqxSYA8UZsZTQdN+PwcoOcAiZTM8C0I=

2. How I run Caddy:

Currently using caddy run or caddy start

a. System environment:

Ubuntu 20.04

b. Command:

sudo caddy run --config ~/temp/Caddyfile

d. My complete Caddyfile or JSON config:

bar.foo.com {
    tls admin@foo.com

    auto_https off

    reverse_proxy localhost:80

3. The problem I’m having:

I want to disable automatic HTTPS redirection because my own service is already listening on port 80. I want to use Caddy to provide access to the service using HTTPS.

However, I am unable to edit my Caddyfile to disable HTTPS redirection

4. Error messages and/or full log output:

unrecognized directive: auto_https

5. What I already tried:

Tried using this directive in my Caddyfile

auto_https off

but then we get the error reported above.

If I remove auto_https directive, I get this other error

2021/07/12 16:22:47.646	INFO	admin	admin endpoint started	{"address": "tcp/localhost:2019", "enforce_origin": false, "origins": ["localhost:2019", "[::1]:2019", ""]}

run: loading initial config: loading new config: http app module: start: tcp: listening on :80: listen tcp :80: bind: address already in use

Also found that Caddy tries to bind to port 80 if I have in the Caddy file

https://bar.foo.com {


bar.foo.com:443 {

That’s because Caddy needs port 80 to solve the ACME HTTP challenge.

I strongly recommend using a different port for whatever you’re proxying to, like 8080 or something.

auto_https is not a directive, it’s a global option. It goes in a block at the top of your Caddyfile:
