Ember app renders blank page when typing in a specific URL

In my Ember app, if I'm developing locally I can directly go to a page by going to the url http://localhost:4200/some/page. I can also navigate to that page within the app itself.

However, after my app is deployed and I go to https://dev.myapp.com I am able to navigate around the site just fine but if I try to go to a url directly (such as http://ift.tt/1GEGSQD) there is nothing rendered in the browser and the DOM is completely empty. But if I enter https://dev.myapp.com/ back into the browser I am able to start navigating the app again.

Would this have to do with how I build or deploy my app or is this something that I might have configured wrong within the Ember app itself?
