Laravel 5 getting started on Heroku

I've gotten laravel to work on heroku before, however following the same and/or similar steps don't seem to work for me anymore.

Brand new Laravel 5 installation after Windows 10 install(so you understand that this was actually completely new). Installed Homestead, checked that the laravel app worked on Homestead Pushed to Heroku. Updated information as follows:

Through CLI:

heroku buildpacks:set http://ift.tt/Mdu4oW
heroku config:set LARAVEL_ENV=heroku
heroku run composer update

added Procfile:

web: vendor/bin/heroku-php-apache2 public

This ends with the server displaying:

Whoops, looks like something went wrong.

How can I enable debugging on Heroku or figure out what went wrong? I looked at the changelog for Laravel and it seems that they've gone from 5.1 to 5.1.4 since I last did this, however I'm not familiar enough with things to know what changes may have caused this issue.
