I think it's possible that you have not turned on any web dynos. 我认为您可能没有打开任何网络测功机。 You can check how many dynos are running using the 'ps' command:
您可以使用“ ps”命令检查正在运行的测功机:
>> heroku ps
You can then scale your application's web dynos like this: 然后,您可以像这样缩放应用程序的网络测功:
>> heroku ps:scale web=1
The above command would set your application to have 1 web dyno. 上面的命令将您的应用程序设置为具有1个Web dyno。
You can refer to this page https://devcenter.heroku.com/articles/getting-started-with-java#scale-the-app for more information. 您可以参考此页面https://devcenter.heroku.com/articles/getting-started-with-java#scale-the-app了解更多信息。
