A previously working Rails app, after a successful Capistrano deploy cycle, stops responding and the server returns the http status code 504.
I was able to successfully access the Droplet by way of SSH. Looking at the logs I noticed the unicorn server was having trouble [re]starting.

Cap Deploy rollback on Net::SSH::Authentication error
I use Nitrous as my primary development environment. The ability to work on any one of a number of projects at any time and from anywhere is simply too convenient to overlook. {As a matter of fact, I am writing this on a Nitrous box from a hospital bed!}
On a site I have been maintaining and continuously updating (on a drogo - Ruby/Rails Nitrous box), my capistrano deploy script failed one day.
