BluemixでScalaPlayアプリケーションを起動するにはどうすればよいですか？

Playフレームワークに基本的なScalaアプリケーションがあり、それをIBMBluemixにデプロイしようとしています。展開中、次のように表示されます。

an instance of the app crashed: failed to accept connections within health check timeout
exit status: -1, CRASHED

私のmanifest.yml

applications:
- path: ./target/universal/scala-bluemix-1.0-SNAPSHOT.zip  
memory: 512M
instances: 1
domain: eu-gb.mybluemix.net
name: TestApp1WithTotalyUniqueName
host: testapp1withtotalyuniquename
disk_quota: 1024M

私はすでにこのリンクをチェックしました：http：//blog.ibmjstart.net/2015/10/27/a-play-scala-server-running-on-ibm-bluemix/それを修正する方法について何かアイデアはありますか？
