I'm trying to deploy my first Rails app but keep getting a `504 Gateway Time-out nginx` error all the time.
I followed this tutorial meticulously: https://www.digitalocean.com/community/articles/how-to-launch-your-ruby-on-rails-app-with-the-digitalocean-one-click-image
I already spent hours reading other (similar) tutorials as well as my various error logs. Unfortunately, I can't get any information out of those logs, so I don't know what I am missing.
This would be one line from my NGINX error log (the other lines all look virtually the same):
`2014/05/21 10:04:12 [error] 731#0: *216 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 22.214.171.124, server: _, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "mydomain.com"`
Can anybody tell me what I am doing wrong here?
Thanks for any help.
