Caddy only returns 404 Not Found

[jandillmann]

First of all, thank you for providing this helpful script!

However, I'm only getting a 404 error from Caddy:

* Trying 192.168.3.17...
* TCP_NODELAY set
* Connected to 192.168.3.17 (192.168.3.17) port 80 (#0)
> GET / HTTP/1.1
> Host: 192.168.3.17
> User-Agent: curl/7.64.1

* Connection #0 to host 192.168.3.17 left intact
* Closing connection 0

Any ideas on how can I investigate further where the problem is? Opening the jail's URL in the browser only shows a white (blank) page.
I'm running FreeNAS 11.3-RELEASE-p14 and as far as I could see the installation went through without any errors.

From inside the jail, what's the output of caddy --version?

[jandillmann]

root@heimdall:~ # caddy version
(devel)

root@heimdall:~ # caddy build-info
path: github.com/caddyserver/caddy/v2/cmd/caddy
main: github.com/caddyserver/caddy/v2 (devel)
dependencies:
 (devel)

It seems like it is not a release, but the development branch from Github?

Looks like the package maintainers have upgraded the caddy package to Caddy v2. Somewhat unfortunate given its lack of backward-compatibility--I'd thought they were going to use a new caddy2 package instead. If you look at the caddyv2 branch of this script, you can pull the updated Caddyfile from there.

A little progress… Caddy now returns 200 OK, but still no heimdall page…

Inside the jail, curl -v localhost:9000 only returns an empty response:

* Connected to localhost (127.0.0.1) port 9000 (#0)

curl: (52) Empty reply from server

Maybe heimdall itself isn't running correctly?

Caddy v2 took a bit of a rewrite, but #4 should resolve this going forward. To test, on the first line of your Caddyfile, change *:80 to just :80.
