Another student who Can't preview the file in browser

I have seen in the discussions that other people are having the same issue as I am but I haven't seen how they managed to fix the problem.

Here is my code. 

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((request, response) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

I then go to the console and type out 

node app.js

I get exactly as I expect. Server running at http://127.0.0.1:3000/ prints to the console.

Then I press preview button as shown in the video and I get directed to page that says "Workspace Unavailable. This is a preview link for a Treehouse Workspace that is not currently active. If you are the workspace owner, you can launch it again via the Treehouse site."

Any ideas what I am doing wrong?

I got the same error with your code, but it disappeared when I tried:

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World');
});

server.listen(port,  () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

I eliminated the hostname thing and fixed the parameters. You had response, but were calling res. Hope that helps.
