根据Heroku的说法，
如果一个应用有一个免费的web动力单元，并且在30分钟内没有接收到web流量，它将进入休眠状态。
如果您的帐户还有剩余的免费动力单元小时数，那么一旦接收到web流量，它将变为活动状态。
个人帐户每月都会获得550个免费的动力单元小时。除了这些基本小时数外，通过信用卡验证的帐户每月还将获得额外的450个小时，添加到月度免费动力单元配额中。这意味着如果您使用信用卡验证您的帐户，您每月最多可以获得1000个免费的动力单元小时。
确保您还没有使用掉您的1000个免费小时！这显然不是情况，因为您的应用程序已经重新启动！
流量可能是问题的原因！
英文:
As stated by Heroku
If an app has a free web dyno, and that dyno receives no web traffic in a 30-minute period, it will sleep.
If your account has free dyno hours left then it will become active as soon as web traffic is received.
Personal accounts are given a base of 550 free dyno hours each month. In addition to these base hours, accounts that verify with a credit card will receive an additional 450 hours added to the monthly free dyno quota. This means you can receive a total of 1000 free dyno hours per month if you verify your account with a credit card.
Make sure you haven't utilized your free 1000 Hours!! which is pretty evident is not the case since your app restarted!!
The traffic might be the issue!
