Solved as Missing Procfile

If you are seeing this error message on your new Heroku Application, this is the reason why you are probably seeing this error. It happened to me.

Forbidden You don't have permission to access this resource.

If you look at your application, you may have forgotten to include a Procfile in your projects. To add a Procfile is easy. If you are using Linux or MAC, you can send this command:

$ touch Procfile

Add the following line to the Procfile:

$ echo "web: vendor/bin/heroku-php-apache2 public/" > Procfile

Now, try again pushing the project to Heroku again.
