Unable to run Ghost using forever

Question

I followed the official Ghost docs (here) for how to install and run forever on my AWS free-tier Ubuntu box as follows:

Installed forever with sudo npm install forever -g as the ubuntu user. Start with NODE_ENV=production forever start index.js and get:

warn:    --minUptime not set. Defaulting to: 1000ms
warn:    --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms
info:    Forever processing file: index.js

I cannot reach my blog, if I execute forever list I get:

info:    Forever processes running
data:        uid  command         script   forever pid  id logfile                        uptime  
data:    [0] _hf3 /usr/bin/nodejs index.js 5034    5036    /home/ubuntu/.forever/_hf3.log STOPPED 

I have also tried the same process as the ghost user:

$ NODE_ENV=production forever start index.js
warn:    --minUptime not set. Defaulting to: 1000ms
warn:    --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms
info:    Forever processing file: index.js

$ forever list
info:    Forever processes running
data:        uid  command         script   forever pid  id logfile                       uptime
