rails deployment using capistrano & torquebox error 502 - ruby-on-rails

Question

I'm running a rails app using JRuby 1.7.4 (1.9.3p392) with Torquebox and trying to deploy to Digital ocean VPS, when I run 'cap deploy' everything runs perfectly fine, however when i try to go to visit the site i still see "502 Bad Gateway nginx/1.1.19
This is my deploy.rb file
`require 'torquebox-capistrano-support'
require 'bundler/capistrano'

end
# This is a weird part. I've found that asset complation with JRuby can really hog up the memory, which can cause the application to crash
# when doing a deploy. So, I like to compile the assets locally and SCP them to the server instead.
# Just make sure you've commented out the load deploy/assets in your Capfile.

I just ran the tutorial again...not really sure, but it looks like Capistrano is not starting Torquebox.
Try ssh'ing into the box and starting it with:
sudo service jboss-as-standalone start
also look at the torquebox log at /var/log/jboss-as/console.log .. is that throwing any errors?
