node server not responding to requests
<p>I have a simple node server that had been running and handling requests smoothly until I came home for the holidays.  Now, it appears to be loading, but does not respond to POST/GET requests.   By this I mean that when I start my server (through calling <em>node app.js</em>) the console prints out that the server is listening on the specific port, and when I visit <a href="http://localhost:8000/" rel="nofollow noreferrer">http://localhost:8000/</a>, I see "hello" in response.  However, when I try to make requests to my server via Postman or through an XMLHTTPRequest (things that worked smoothly before I moved locations), I get an error.  </p>

<p>Is there something wrong with my code?  Is it possible that my wifi and connection at home is different from my workspace?</p>

<p>See the important code in my server below:</p>

<pre><code>var express = require('express');
var app = express();
var bodyParser = require('body-parser');

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended: true
}));

app.get('/', function(req,res){
    res.send("hello");
})

app.listen(8000, function () {
   console.log('App listening on port 8000!');
});
</code></pre>

<p>thank you very much!</p>
