Make Sure your Nginx config's passenger_ruby is your Rails App's ruby version.

if you install for passenger's way and use RVM, it will be usr/local/rvm/gems/ruby-2.1.2/

    passenger_root /your-ruby-version/gems/passenger-4.0.50;
    passenger_ruby /your-ruby-version/wrappers/ruby;

hope this information will help :)

From what i am guessing , nginx isn't able to connect to your application . Lets do so using Capistrano

Install the gem , and then run - bundle exec cap install

Based on an earlier question i had asked , copy over the contents from the deploy and staging files in your folder . Set the addresses accordingly and try it out . Do let me if i can help further .
