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:

Docker , db builtin n8n version the latest
os : ubuntu 22

My preferred way to run any docker container air-gapped is to create a new overlay network with

docker network create --internal no-internet

and then run the container air-gapped with

docker run -d \
  --name n8n \
  -p 5678:5678 \
  -v n8n-data:/home/node/.n8n \
  -e N8N_DIAGNOSTICS_ENABLED=false \
  --network no-internet \
  n8nio/n8n:latest

However with a private network, port forwarding will not work, since the host does not have a route to the private network (likely the issue you are facing).

You can however either

1. use the IP address of the container to access the container directly (you’d need to set -e N8N_SECURE_COOKIE=false), or
2. setup a reverse proxy container that has access to this private network, as well as a public network, so that you can access n8n via this. I usually use Traefik or Caddy for this.

BTW,

@yaniv-k8s

-e N8N_BASIC_AUTH_ACTIVE=true
-e N8N_BASIC_AUTH_USER=admin
-e N8N_BASIC_AUTH_PASSWORD=password

You can delete these.
n8n removed basic auth support over a year ago with the release of 1.0.0

@yaniv-k8s

-e N8N_DISABLE_TELEMETRY=true

This has never been an env variable in n8n.
Can you please tell us where you found this documented, so that we can get it fixed
