Node.js app not loading on Ubuntu 12.04 - this site cant be reached

Question

I'm developing a node.js (SEAN.JS) app. On my local machine the app works normal at localhost:3000, After I run grunt, But on my server (Ubuntu 12.04 - angular.pling.cc:3000) it doesnt.

The error I'm recieving is:

"This site can't be reached. angular.pling.cc took too long to respond."

Any help would be much appreciated.

Answer 1

solved. i redirected port 80 to 3000 with this command:

sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3000

as suggested here: Best practices when running Node.js with port 80 (Ubuntu / Linode)
