"Incomplete response received from application" from nginx / passenger

I tried to deploy my rails app on nginx and ubuntu via capistrano like the tutorial on the page https://gorails.com/deploy/ubuntu/14.04. but at the end i get an error message: 

Incomplete response received from application

in my browser. this is probably an error from passenger, but how can i figure out what to do?

Solution

  • Your rails_env production don't have required set up,probably missing secret_key_base.

    Open /etc/nginx/sites-available/default and change the rails_env to development:

    rails_env production;
        to
rails_env development;

    If the app is loading it's not a passenger issue.

    Production Solution:

    1. Enter your app root
    2. run: rake secret
    3. copy the output
    4. go to /yourapp/config/secrets.yml
    5. set the production secret_key_base

    Restart the passenger app : 

    touch /yourapp/tmp/restart.txt
