Running through Proxy in Sub Folder

Describe the problem/error/question:

I’m trying to run the official N8N Docker container on my unraid machine, behind the SWAG reverse proxy.

I’ve spent a few days researching this and have a mess of environment variables defined, and I have no idea what’s valid, deprecated, or just plain wrong anymore:

docker run
  -e TZ="America/New_York"
  -e HOST_OS="Unraid"
  -e 'N8N_SECURE_COOKIE'='false'
  -e 'N8N_PATH2'='/n8n/'
  -e 'GENERIC_TIMEZONE'='America/Toronto'
  -e 'WEBHOOK_URL'=''
  -e 'SUBFOLDER'='n8n'
  -e 'N8N_HOST'=''
  -l net.unraid.docker.managed=dockerman
  -p '5678:5678/tcp'
  -v '/mnt/user/appdata/n8n/':'/home/node/.n8n':'rw' 'n8nio/n8n'

The command finished successfully!

If I disable the N8N_PATH variable, the GUI loads in private address space:

On the public address side, the page loads blank:

Looking at the Chrome Dev Tools, I can see that resources are trying to load from the root sub domain:

Enabling the N8N_PATH variable to /n8n/ breaks my internal address access (it just loads blank), and doesn’t change the behaviour on the public side.

I should note that when I listen for a webhook event, it has the right URL pre-populated:

Here’s a copy of some configs in SWAG:

    • /swag/nginx/proxy-confs/n8n.subfolder.conf
## Version 2023/02/05
# Make sure that your n8n container is named appropriately (e.g., n8n).
# Ensure n8n is set to work with the base URL /n8n/.

location /n8n {
    return 301 $scheme://$host/n8n/;

location ^~ /n8n/ {

    proxy_pass $upstream_proto://$upstream_app:$upstream_port;

    # Additional proxy settings such as headers go below this line, leave the blank line above.

# REMOVE THIS LINE BEFORE SUBMITTING: Some proxies require one or more additional location blocks for things like API or RPC endpoints.
# REMOVE THIS LINE BEFORE SUBMITTING: If the proxy you are making a sample for does not require an additional location block please remove the commented out section below.
location ^~ /n8n/api {
     include /config/nginx/proxy.conf;
     include /config/nginx/resolver.conf;
     set $upstream_app n8n;
     set $upstream_port 5678;

     proxy_pass $upstream_proto://$upstream_app:$upstream_port;

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:

hello @rayray14

Well, seems the N8N_PATH is not applied to some resources, but I don’t know if that is the intended behavior or not.

@Jon can you please look into it?
