Question

I’m following the tutorial here:
I’ve gone through all the steps. My app has a config.ru, a gemfile and a file that just says go! This was just to test the app running on heroku to see how it handled. Sadly I’m getting a very strange error.

Below is my git push as per the tutorial

git push heroku master
Counting objects: 9, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (5/5), done.
Writing objects: 100% (5/5), 596 bytes, done.

Seems simple enough. But the heroku ps gives

-------  --------------  ------------------------------------

Naturally enough I checked the logs but they may as well be in arabic.

I did think that heroku was running apps on ruby 1.9.2 but thats not important. It would seem I’m missing some sort of ssl cert or variable. I definitely haven’t used any SSL based functions in my ‘go.rb’ script but it still seems to require something.

Can anyone point me in the right direction here?

The config.ru

require './go'
run Sinatra::Application

This issue really haunted me for a while. I still haven’t got to the bottom of the problem but It has been fixed and hasn’t resurface.

The sinatra application just would not start. After checking the logs, I found the word SSL popping up a lot

I wrote another smaller program just to test on Heroku and It had the same error.

I followed the tutorial here and It seemed to resolve the error.
