Puma restart fails on reboot using EC2 + Rails + Nginx + Capistrano

I have successfully used capistrano to deploy my rails app to Ubuntu EC2. Everything works great on deploy. Rails app name is deseov12 My issue is that Puma does not start on boot which will be necessary as production EC2 instances will be instantiated on demand. Puma will start when deploying via Capistrano, it will also start when running

cap production puma:start

on local machine.

It will also start on server after a reboot if I run the following commands:

su - deploy
[enter password]
cd /home/deploy/deseov12/current && ( export RACK_ENV="production" ; ~/.rvm/bin/rvm ruby-2.2.4 do bundle exec puma -C /home/deploy/deseov12/shared/puma.rb --daemon )

I have followed directions from the Puma jungle tool to make Puma start on boot by using upstart as follows:

Contents of /etc/init/puma.conf and /home/deploy/puma.conf

# /etc/init/puma.conf - Puma config

# This example config should work with Ubuntu 12.04+.  It
# allows you to manage multiple Puma instances with
# Upstart, Ubuntu's native service management tool.
#
# See workers.conf for how to manage all Puma instances at once.
#
# Save this config as /etc/init/puma.conf then manage puma with:
#   sudo start puma app=PATH_TO_APP
#   sudo stop puma app=PATH_TO_APP
#   sudo status puma app=PATH_TO_APP
#
# or use the service command:
#   sudo service puma {start,stop,restart,status}

However, I have not been able to make Puma start up automatically after a server reboot. It just does not start.

I would certainly appreciate some help

EDIT: I just noticed something that could be a clue:

when running the following command as deploy user:

sudo start puma app=/home/deploy/deseov12/current

ps aux will show a puma process for a few seconds before it disappears.

deploy    4312  103  7.7 183396 78488 ?        Rsl  03:42   0:02 puma 2.15.3 (tcp://0.0.0.0:3000) [20160106224332]

this puma process is different from the working process launched by capistrano:

deploy    5489 10.0 12.4 858088 126716 ?       Sl   03:45   0:02 puma 2.15.3 (unix:///home/deploy/deseov12/shared/tmp/sockets/puma.sock) [20160106224332]
