Ember.js - localhost:4200 looks for index.html

I just created a new ember app and I'm having trouble getting started. I created a new route: index, and for a while, localhost:4200 was correctly loading index.hbs in my app/templates folder. For some reason, now when I load localhost:4200, it's looking for an index.html file. Here's the error:

Error: ENOENT: no such file or directory, stat '/home/tom/http://ift.tt/2brQu8u

I'm not really sure what's causing this. I haven't made any chances to my router. Does anybody know why it's looking for this file instead of just loading the index route?

Thanks.
