When trying the Heroku url:
Application Error
An error occurred in the application and your page could not be served. Please try again in a few moments.
If you are the application owner, check your logs for details.
Heroku log:
2016-06-30T09:50:50.412023+00:00 heroku[router]: at=error code=H10 desc=“App crashed” method=GET path=“/” host=APPNAME.herokuapp.com request_id=5477cc40-eb39-4dd3-9a3a-14d1f3ad0022 fwd=“IP” dyno= connect= service= status=503 bytes=
Any ideers on what the problem is?
Well, a 503 error is “service unavailable”:
503 Service Unavailable
The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state. (wikipedia)
Are you on a free tier, which has been shut down?
So, those dinos sleep after 30 mins of inactivity - maybe it went to sleep and didn’t wake up quickly enough?
Are those the only logs you have? It should show a little more about the reason…
You’re using this buildpack for deployment? Find out by using this command:
heroku buildpacks --app APPNAME
2 buildpacks? You only need the meteor one.
And do you have any more logs? It should show a reason why it crashed.
i’m new to Heroku so I dont know where to get more crash rapports
Ok, no problem 
If you want to see your logs you can type this:
heroku logs --tail --app APPNAME
That should show you a live streaming log.
Your build succeeded? https://dashboard.heroku.com/apps/APPNAME/activity and then click on view build log

Hello there I have the same problem and I have two buildpacks
I try to restart my heroku but still no changes, any suggestion?
This is a Meteor forum. I’m not familiar with buildpacks you mentioned. You might want to try Stack Overflow.
