Caddy service fails when not logged in

Help
1

1. The problem I’m having:

I installed Caddy with go 1.21.1 using only the caddy-wol plugin, updated from Caddy 2.7.4 to 2.7.5 and the issue persisted. Im doing this in Debian 11 on a pi.

When I run systemctl enable --now caddy it works, but then when I reboot I see it always fails with status=2/INVALIDARGUMENT. I am struggling to find any relevant information to fix this and I believe I have everything set up correctly because when I remove --config /etc/caddy/Caddyfile it does run as expected.

2. Error messages and/or full log output:

I’m not really sure how to copy the text from the pi to here so I will add the lines I think are relevant manually and figure out a way to export the rest if that’s not enough or if requested

Process: 473 ExecStart=/usr/local/bin/caddy run --environ --config "/etc/caddy/Caddyfile" (code=exited, status=2)

3. Caddy version:

I built with go 1.21.1, caddy 2.7.5, on Debian 11 on a pi

4. How I installed and ran Caddy:

I followed the instructions and installed go, xcaddy, etc.

a. System environment:

Debian 11 on a pi

b. Command:

sudo systemctl enable --now caddy

c. Service/unit/compose file:

systemd

d. My complete Caddy config:

I am able to run this with the config which I have validated, I am using only reverse proxy and caddy-wol

5. Links to relevant resources:

Thank you

Which instructions, exactly?

What do you see when you run caddy version?

Your logs should show the Caddy version it’s running because of --environ. Make sure that’s also 2.7.5.

Please show your full logs, not just sections of it. Make sure to read https://caddyserver.com/docs/running#using-the-service, we have a recommended command for looking at your logs.

Sorry, it took me a little while but I was able to get the logs and can get more things now.

Logs from journalctl from last boot. You can see after I logged in I ran it and it worked. I tried to redact my urls btw to a1, a2, a3, a4

These instructions - Build from source — Caddy Documentation

plus a lot of blogs and posts from various places including here trying to debug

Edit 2: sorry i am disorganized on all this I appreciate your help very much.
I see 2.7.5 when I run caddy -v which I found was only added in 2.7.5

Ah okay, that’s a bug with the caddy-wol plugin then. It’s failing in that plugin’s code. Please reach out to the plugin’s maintainer for help.

Thank you so much for your speedy replies and I apologize for not including the full log output in my initial post, I forgot I had set up a firewall lol

I opened an issue with the plugin repo, here is a link for any future readers Failing to launch caddy with only caddy-wol plugin on caddy 2.7.5 in go 1.21.1 on debian 11 · Issue #13 · dulli/caddy-wol · GitHub

GPT saved the day, after probing it about my error from the log snippet provided by francislavoie it told me about the middleware Cleanup() func. From there I realized it was failing to open a udp socket before login, but worked after login. So I kept asking questions and eventually it provided me with an answer + source(see above link).

My unit file needed to be like this.
After=network.target sockets.target network-online.target multi-user.target

Thank you again for your assistance!!! you guys are awesome

Glad you figured it out. In the future, filling out the help template properly would have made this obvious, since our official unit file has those properties. :slight_smile:

@matt Agreed, I was impatient about figuring out why I couldn’t transfer my log files which I regret.

This was the unit file I was using, from the Keep Caddy Running page

However, I believe the After=... sockets.target multi-user.target was what I specifically needed to add for the caddy-wol plugin to work as a system service for debian/linux, and it does not need to be in there unless a plugin is attempting to set up a socket before that is available or perhaps something else.

I’m not sure that this type of plugin’s specific needs would fit in the official unit file but perhaps adding After=... multi-user.target might be worthwhile. I’m inexperienced in this domain and will leave it to the experts!

Thank you to both of you again for all you’ve done for Caddy!

Oh, I see, multi-user.target and sockets.target are not in the unit file; I scanned and only saw the other ones which are in our unit file already. Sorry about that.
