N8N Behind caddy

[wouterverduin]

Hi all!

The last days i have been desperately trying to get n8n running behind my caddy reverse proxy.

The general steps:

1. Run the proxmox lxc n8n shell command
2. Set a local IP (e.g. 192.168.1.80)
3. Check local webUI from another PC at 192.168.1.80:5678 and see it working
4. Setup caddy: See snippet below
5. Get ERR_SSL_PROTOCOL_ERROR error at n8n.something.com

Caddyfile snippet:
n8n.something.com {
reverse_proxy 192.168.1.80:5678
}

What have i tried:
Used this tutorial: https://github.com/sfnemis/proxmox-traefikproxy-cloudflaretunnel
Attempted to add all these environment variables in the container service but still the same error. I noticed that the webhook also isnt updated when e.g. i use a telegram node it still refers to localhost.

Is there anyone who can point me in any succesfull direction to get it running behind caddy?
