When running N8N Behind Http proxy, it does not work and gives bad gateway error, here the issue is that the requests are going properly and proxy is responding properly to the messages but N8N shows Bad Gateway error.

## What is the error message (if any)?

502 - "\n\n\<meta type="copyright" content="Copyright (C) 1996-2019 The Squid Software Foundation and contributors"\>\n\<meta http-equiv="Content-Type" content="text/html; charset=utf-8"\>\nERROR: The requested URL could not be retrieved\n\<style type="text/css"\>\<!-- \n /\*\n \* Copyright (C) 1996-2020 The Squid Software Foundation and contributors\n

I am using simple workflow to send messages via slack to channel.

@Vikas_Bukhari, did you set the `N8N_PROXY_HOPS` environment variable as stated in [here](https://docs.n8n.io/hosting/configuration/environment-variables/deployment/)?

It does not only happen with Slack, It happens with all outbound http / https calls. @Knight

@Vikas_Bukhari Try this:

```auto
version: '3.3'

services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    container_name: n8n
    ports:
      - "5678:5678"
    environment:
      - N8N_ENCRYPTION_KEY=db1cef92-ee4d-4b83-a807-999ea50e573b
      - N8N_PROXY_HOPS=1
      - WEBHOOK_URL=https://<NGROK_DOMAIN>
      - N8N_DIAGNOSTICS_ENABLED=false
      - N8N_VERSION_NOTIFICATIONS_ENABLED=false
      - N8N_TEMPLATES_ENABLED=false
    volumes:
      - ~/.n8n:/home/node/.n8n
    restart: unless-stopped
    stdin_open: true
    tty: true

```

Make sure to replace `https://<NGROK_DOMAIN>` with the url you received from the proxy. Check also if the proxy is forwarding it’s requests to `localhost:5678`.

Make sure your proxy is configured to pass the host name, for apache that is:

ProxyPreserveHost On

and the full proxy config is:

```
RewriteEngine On
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
RewriteRule ^/?(.*) "ws://localhost:5678/$1" [P,L]
RewriteCond %{HTTP:UPGRADE} !^WebSocket$ [NC]
RewriteRule ^/?(.*) "http://localhost:5678/$1" [P,L]
ProxyPassReverse / http://localhost:5678/
ProxyPreserveHost On

```
