Hi,
our website is currently downed with error code 502 Bad Gateway and our web developer is currently out on Vacation. I am just an IT person on our network and i don;t have web coding knowledge. Hopefully, i can i get here to fix this issue.

here is what i know:
Ubuntu Ruby on Rails on 14.04 (Nginx + Unicorn)

When i login to digital ocean, i see the droplet status was off , then I turned it on, but website still shows 502 Bad Gateway, i then tried to power cycle it, still the same thing.
i tried the website by IP address and no luck. i can ping the IP address though.......any idea?
