Unable to connect on deploying a rails app with Nginx, Capistrano and Puma on Ubuntu 16.04

Hello:

I am trying to deploy my rails app on Ubuntu 16.04 adapting this tutorial.

I have gone through all the steps and when I visit the IP address I get “unable to connect, Firefox can’t establish a connection to the server at IP address”

I have checked my logs and none of them show any sign of errors: nginx.access.log
