I have been having some issues with running a Rails app using the Thin web server over SSL on Heroku. One thing that I think may be causing my issues is that I am not starting the thin server using ssl (such as shown here and here). However, I do not know the correct syntax to boot a thin server using ssl on Heroku. Here are the different procfile variations I have tried with no luck:
web: thin start --ssl -p $PORT
web: bundle exec thin start --ssl -p $PORT
web: bundle exec rails s thin --ssl -p $PORT
web: thin start --ssl
