5,672 PointsIt looks to me like maybe you're looking at a workspace that has timed out. try refreshing the workspace by pressing control-r. If that doesn't work then go back to the treehouse website and re-open the workspace from there. It can be found by clicking the icon on the left of the screen that is a square with <> inside of it. You might not be able to see it unless your window is maximized.

7,857 PointsHi, I was also facing the same issue. I then noticed that the code I was wishing to preview required a server to run on, which I had not initialized.
If you too are on a track learning a course which requires you to implement a code on a server, check if you haven't already initiated the server before previewing. For the people making a dynamic website using node you can probably type in:
node <javascript-code-name-that-creates-a-server>.js
on the console and then preview... Hope this helps. Btw in my case I had to run
node app.js
