Another question for that matter, would it possible to add an option to include files under "caddy.d" inside a domain matcher? In my case it would create a Caddyfile like this:

Code Select Expand


*.edholm.cc {
  # Options
  import /usr/local/etc/caddy/caddy.d/*.conf
  # Or perhaps lookup files with the configured domain as a prefix, like *.edholm.cc.conf
}

Mainly this is to make external automations able to add individual handlers as separate files for an existing domain. Benefit is that the plugin keeps track of the TLS cert and some other FW configured things, and, in my case, Ansible could still add configurations without requiring opening the webui manually. This should not break any existing plugin functionality, I think, except if you add files which handles the same subdomains as the plugin is set up to handle already.

Auto HTTPS is off thats why there is no port 80.

Change the setting in general settings.

It needs to be on for the automatic http to https redirect even if you dont use lets encrypt.

Ah, thanks! That explains the lack of port 80! And indeed, checking that box immediately redirected http to https. However, perhaps the help text for this option should be slightly updated? It currently states:

Select the Auto HTTPS option. "On (default)" creates automatic certificates using "Let's Encrypt" or "ZeroSSL". "Off" turns all automatic certificate requests off.

Something mentioning the redirect could be added?

Regardless, I am still running into the issue I had when prodding https before:

The Let's encrypt TLS cert is setup inside OPNsense (this guide is probably the closest to what I have: https://sysadmin102.com/2023/05/create-lets-encrypt-wildcard-certificates-on-opnsense-with-acme-client/) in order to re-use the certificate elsewhere in the network. However, despite the plugin being setup to use this certificate it does not seem able to serve it:

Does the logs above tell you anything? I don't get why it would not find a matching certificate, because the one I have is setup for "*.edholm.cc". What could I be missing for that not to work?

Thanks -- I ensured that it was still checked.

I could say more if I can see the Caddyfile. But right now no idea really.

The Caddyfile looks like this (did not find any spoiler tag to compress my message):

sockstat -l | grep -i 80
sockstat -l | grep -i 443

I can see that Caddy has managed to bind to port 443, but not 80. AFAICT no other service has taken port 80 either: Doing curl on localhost:443 results in "error:0A000438:SSL routines::tlsv1 alert internal error". Output of sockstat for port 80:

service caddy status

Caddy appears to be running just fine: "caddy is running as pid 72385."

service caddy restart
service caddy reload

This did perform a clean restart and reload of Caddy, as opposed to asking Caddy to reload itself. So that's nice to know! Still, it unfortunately did not make any difference.

I noticed that I had used an older version of the plugin, so just to be safe I also did reset most settings and applied it again to see if the update had fixed something related to what I attempted to setup. But still no success.

Hi!

I tried setting up the Caddy plugin but ran into some issues. Just setting up a basic reverse proxy does not seem to work for me when following the guide. It doesn't give me any errors from the GUI and the Caddy service appears to be running properly, but trying to run

Code Select Expand

caddy reload --config /usr/local/etc/caddy/Caddyfile results in an error not displayed elsewhere:

Error: sending configuration to instance: performing request: Post "http://127.0.0.1:2019/load": dial tcp 127.0.0.1:2019: connect: connection refused

Maybe it is not possible/supported to reload caddy this way? Even though the service appears to be up, it does not seem able to connect properly, given:

What could I be missing? Thanks in advance!
