localhost will not load

When I type 'nodemon' on the command line, I get the message "App listening on port 3000!", so everything seems fine but the localhost will not load and it doesn't even thrown an error. It just tries to load indefinitely. I eliminated all of the subdirectories (V2, V3 etc.) so I imagine maybe it has something to do with that, but I can't identify the exact problem. Please help. Thanks. Here is a link to my repo: https://github.com/schnauzerPower/Async

Did you checked without nodemon? try with " node app.js," or check your browser issue like chrome and firefox. clean cach browser. Note look at terminal nodemon when you refresh browser may be show error later on the nodemon terminal.

In your app.js file, you have to serve up your page. 

// respond with "hello world" when a GET request is made to the homepage
app.get('/', function (req, res) {
  res.send('hello world')
})

I had the same issue here. She shows you the page working at the beginning of the video, making you think it should just load up and work, but you haven't written the code in the app.get method yet.
