Q&A
Herokuのログを確認してエラーの詳細を追記ください（質問文の中に追記ください）。
pythonを独学で勉強しています。flaskでアプリを開発中です。
ログインしたのち、出勤パターン（30分、60分、90分）を選択して、終了予定時間
を出力するという流れです。
ローカル（127.0.0.1）ではうまくいきましたが、
herokuでの動作がうまくいきません。
デプロイはできるのですが、最初のログインページを表示できず、Application Errorとでます。
修正方法ご教示いただければ幸いです。

エラーログ追記しました。Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launchという部分があやしいと思いますが、いかがでしょうか？よろしくお願いいたします

app.run()呼出しを少し変更する必要があるようです。
python
1 port = int(os.environ.get("PORT", 5000)) 2 app.run(host="0.0.0.0", port=port)
