解决方法
Heroku的支持回答建议使用heroku restart手动重启你的应用程序.他们现在正在解决这个问题.
@H_404_4@Hi,A process management error on our side caused some crashed apps only running 1 web dyno to be reported as “idle” even though they were actually crashed. This means that the crashed dyno was never restarted,causing subsequent requests to fail. We’ve identified this problem and are implementing a fix. If your app is still unresponsive,please try restarting it with the heroku restart command. Please let us know if you need more help. Thanks,Heroku Support
