Unable to access server in Node chat application



I haven’t encountered this problem before:

Just running the provided chat application i get:

node server.js
info - socket.io started
Chat server listening at

but nothing shows up in the preview window

Thank you


Tough to tell what’s going on with the info given here but have a look at the browser console and see if there are any issues showing up there.

Also, what is the application preview page looking like? Is it blank? Is there a Cloud9 error? Any other stuff showing up?
