Hello this is my first time working with a VPS. I've managed to follow the instructions from this tutorial https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-14-04 but once I reached the "Manage Application with PM2" everything stopped working. Basically my web app works when I run "node index.js" (index.js being where my express app starts) but when I try "pm2 start index.js" it says it's started but I can't reach it from my browser. It says it's online http://i.imgur.com/U6lgxk0.png but it's not. Help please.
