N8n lost connection to the server while running in QNAP

[ivan_zinov]

• I am trying to run n8n on my QNAP. The thing is, QNAP offers a software named Container Station, where I can run all of my Docker containers. I can run n8n on the QNAP after configuring n8n through a reverse proxy via https.
  The issue occurs when I try to execute a node, and it says it has lost connection to the server. After checking the n8n logs, I am not seeing any errors, nor on my reverse proxy nginx. I am not able to see any error logs, at least to point myself in the right direction to fix the issue. Here is my configuration of n8n using a Docker Compose file that I loaded inside of my Container Station as an Application, and it loads the container with this configuration and persists the data in an external volume

services:
n8n:
container_name: n8n
image: docker.n8n.io/n8nio/n8n:latest
restart: unless-stopped
ports:

• “5678:5678”

Please share your workflow

It is a manual click that executes a python code to print an array in the output console, but can be print(‘hello world’)

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

hello @ivan_zinov

Most likely, your nginx doesn’t have a wss-related configuration for the n8n. Check how to configure WSS in nginx.

You can find more errors by opening the dev console (F12) and checking the network tab

I ended up trying to run it on my Docker Desktop first, and then I replicated the same steps on my QNAP container station. So far, the only difference I am seeing is that I have my volumes at the container app level, and with this Docker-Compose, I was trying to persist the volumes in a shared drive. Maybe it was something related to permissions , now it works
