I use a new Unraid server

I have a tunnel with cloudflare. But I have already released the links that I will use on n8n.

n8n.mysite.com.br
n8nwebhook.mysite.com.br

n8n works in normal mode, only in queue mode, I don’t understand why everything went up, the account is active, but it doesn’t open either through the local IP or through the website.

192.168.10.254:5678
n8n.mysite.com.br

Values ​​that will be in the variables

N8N_EDITOR_BASE_URL = https://n8n.mysite.com.br/
WEBHOOK_URL = https://n8nwebhook.mysite.com.br/
N8N_HOST = 192.168.10.254

I tried too

N8N_HOST = https://n8n.mysite.com.br/

The problem is that I don’t use traefik, so I removed everything related to it.
I use nginx with webUI, and I’ve already configured the domains, because I have other dockers working fine via nginx

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Without seeing the exact config’s its hard to say for sure, I see there is an n8n instance turned off ( not sure if it is part of it ) also do you have it connected to your redis and postgres, as I don’t think it will work without the shared database or a way to connect

Last week I did play around with getting this working, I will give you a link to my docker enviroment ( With all passwords removed, and domains removed ext… )

I updated the first post with all stacks.

Postgres and Redis working and connected because I use them in other applications.

To install n8n in a row you need to install it three times (Editor, Webhook, Worker)

The other installation called n8n (fourth) is the one I currently use installed in normal mode, but it is turned off.

The problem is that I don’t use traefik, so I removed everything related to it.

I use nginx with webUI, and I’ve already configured the domains, because I have other dockers working fine via nginx

I found help on another forum and solved it like this.
