Hi guys, i have been all day long trying to deploy n8n on my vps with docker without success. I have this docker-compose.yml file:

version: "3"

services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    ports:
      - "5678:5678"
    environment:
      - N8N_HOST=domain.domain.dev
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - WEBHOOK_URL=https://domain.domain.dev/
      - VUE_APP_URL_BASE_API=https://domain.domain.dev/
      - VUE_APP_URL_BASE_WEBSOCKET=wss://domain.domain.dev/
      - N8N_WEBSOCKET=true
      - N8N_WEBSOCKET_PATH=/rest/push
      - N8N_EDITOR_BASE_URL=https://domain.domain.dev/
      - N8N_RUNNERS_ENABLED=true
      - N8N_LOG_LEVEL=debug
      - GENERIC_TIMEZONE=Europe/Madrid
      - NODE_ENV=production

    volumes:
      - ~/.n8n:/home/node/.n8n

And i am using Nginx with this config:

server {
    server_name domain.domain.dev;
    location / {
        proxy_pass http://localhost:5678;
        proxy_http_version 1.1;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Upgrade $http_upgrade;
    }


    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/domain.domain.dev/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/domain.domain.dev/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = domain.domain.dev) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    server_name domain.domain.dev;
    listen 80;
    return 404; # managed by Certbot


}

And getting this error on console when in Workflow:

index-BpdkKRP4.js:293262 [WebSocketClient] Connection lost, code=1008
onConnectionLost @ index-BpdkKRP4.js:293262Understand this warning

If anyone can help me, i will appreciate it a lot :slight_smile:

You could try adding the following

proxy_set_header host $host;

and I think the VUE ENV’s don’t work in Docker Docs

and N8N_WEBSOCKET & N8N_WEBSOCKET_PATH I haven’t found these in the ENV’s docs, maybe they don’t work either or they don’t exist

Error 1008 just confuses me as this is a policy error.
