How to deploy on Heroku?

[Zythyr]

I am trying to the run the signalmaster on Heroku free version for development testing.

After generating the SSL certs, I removed the *.pem from .gitignore and pushed to Heroku app. When I do heroku logs it clearly shows the build was successful and also shows a port number. However, when I go to the actual URL (ex: https://immense-chamber-12345.herokuapp.com:49368/socket.io) the page does NOT load.

On my local machine, when I go to http://localhost:8888/socket.io, everything works fine.

Is there some issue with SSL? According to this module, it says Heroku blocks the SSL. https://www.npmjs.com/package/force-ssl-heroku
