http.get doesnt work [error]

var http = require("http");
var username = "chalkers";

function printMessage(username, badgeCount, points) {
  var message = username + " has " + badgeCount + " total badges and " + points + " points in javascript";
  console.log(message);
}  

var request = http.get("http://teamtreehouse.com/" + username + ".json", function(response) {
  console.log(response.statusCode);
});

request.on("error", function(error) {
  console.error(error.message);
});

This is my code and I dont see anything wrong with it. I get this error message:

treehouse:~/workspace$ node app.js

events.js:72
throw er; // Unhandled 'error' event
^
Error: getaddrinfo ENOTFOUND

getaddrinfo ENOTFOUND
treehouse:~/workspace$ node app.js

Hmm. I copied and pasted your exact code into a workspace, and it logged a 200 (it worked).

Try closing the workspace and reopening it. There might be something wrong with the port.

Click on the "workspaces"-tab on the lefthand side and create a brand new workspace with nodejs environment. That worked for me.

same problem, still no solution for me even after trying on Chrome, Firefox and Safari. I'm running linux if that matters. I think it's a workspace bug.

I'm having the same issue. I did the first part of the course fine and was receiving statusCode 200s. I left and came back a half day later and now I'm running into getaddrinfo ENOTFOUND errors. I tried reopening workspace as well as changing browsers from Chrome to Safari. Nada.
