この英雄クラッシュの原因は何ですか？エラーコード= H10

Question

私はこの質問の過去の記事を見てきました。多くの人がherokuを再起動したり、dynosを再起動したり、var PORT = process.env.PORTを使用していることを示唆しています。 3000.私はこれらのすべてをやったが、私のアプリはまだクラッシュします。アプリケーションは、ノード/ express sequelize/auth0を使用して実行されます。

いずれかの提案がありますか？ありがとう！

それはクラッシュだなぜあなたのログが明確にあなたを教えて：

2017-09-08T02:11:37.293030+00:00 app[web.1]: Unhandled rejection . 
SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306 

あなたのSQLサーバーに接続できません。

見た目から、あなたは127.0.0.1:3306に接続しようとしていたようですが、これは動作しません。 127.0.0.1またはlocalhostがローカルIPです。

Heroku's Postgresアドオンにセットアップ/接続するか、Amazon RDSなどの外部SQLサービスを使用する必要があります。
