Hi Guys, would like to ask. I am currently having some problem when launching the nodeJS with the node-red. I just try the example the code from the node-red website, but it seems to getting the error of web socket problem. I am not sure if whether I need to setup manually or is there something I need to do?

I am running it on local host:

**My Node JS Code:**

```auto
var http = require("http");
var express = require("express");
var RED = require("node-red");

// Create an Express app
var app = express();

// Add a simple route for static content served from 'public'
app.use("/", express.static("public"));

// Create a server
var server = http.createServer(app);

// Create the settings object - see default settings.js file for other options
var settings = {
  httpAdminRoot: "/red",
  httpNodeRoot: "/api",
  userDir: "/nodered-stuff/nol/.nodered/",
  functionGlobalContext: {}, // enables global context
  editorTheme: {
    page: {
      title: "GDESK Node-RED",
    },
    header: {
      title: "GDESK Node-RED",
    },
  },
};

// Initialise the runtime with a server and settings
RED.init(server, settings);

// Serve the editor UI from /red
app.use(settings.httpAdminRoot, RED.httpAdmin);

// Serve the http nodes UI from /api
app.use(settings.httpNodeRoot, RED.httpNode);

server.listen(8000);

// Start the runtime
RED.start();

```

Are you running behind any kind of proxy like nginx? If so, you need to configure it to allow websocket requests through.
