Hi Andrew Chalkley, I'v isolated the timeout to http.get at the following url: http://teamtreehouse.com/paulwagner.json
When i browse to it directly with my browser i have no problem getting to it. When i substitute http://google.com in that same http.get call it returns no problem. I suspect there maybe something blocking the communication between your app server and your api server.

My page actually loads the error page and not the profile page. Im assuming its because Im getting a 404 error.
Colin Stodd
6,257 PointsBut Paul to answer your question. You might have to add an "s" to any place where you have http://www.teamtreehouse.com"
var request = http.get("http://teamtreehouse.com/" + username + ".json", function(response) {
var body = "";
Treehouse added the "s" security recently. Not sure why they haven't upgraded the videos to reflect this.

I also want to point out that I'm using the project download files. Even the last folder won't work, all it executes is the username back without any styling.
Colin Stodd
6,257 PointsSorry I can't find how to edit my posts; but I meant (above) the "s" as in "http(s)", so anywhere http://www.teamtreehouse.com is included in your code, you need to change it to https://www.teamtreehouse.com
