我认为这个错误与超时有关。
在 H13 错误的 heroku 页面中引用了这个解释。
"One example where this might happen is when a Unicorn web server is configured with a timeout shorter than 30s and a request has not been processed by a worker before the timeout happens. In this case, Unicorn closes the connection before any data is written, resulting in an H13."
所以我认为这个回复可以帮助您解决问题。
也有这个错误。不是由于超时，因为它会立即出现。我刚刚对 requirements.txt 进行了更改，包括更新了某些软件包的版本。当我在 Github 上时，我将 requirements.txt 文件回滚到以前的版本，这解决了问题。我的猜测是您的需求文件导致了问题（尽管很难将其中的特定行与错误隔离开来）。
运行 在尝试部署通过遵循 MDN Docs. Was able to resolve it by lowering the Django version to 2.2.10. Here is the requirements.txt file and the deployed app 创建的应用程序时遇到了同样的问题，因为它在本地工作。如果您不是专门出于某种目的使用 Django 3，那么将它降低到 2.2.10 应该没问题。 MDN 上的教程也是使用 django 2 制作的。
我的网站和管理页面在本地工作，但是当我尝试在 Heroku 网页上访问我的管理页面时，我收到一个应用程序 error:H13。

Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))

我认为这个错误与超时有关。 在 H13 错误的 heroku 页面中引用了这个解释。 "One example where this might happen is when a Unicorn web server is configured with a timeout shorter than 30s and a request has not been processed by a worker before the timeout happens. In this case, Unicorn closes the connection before any data is written, resulting in an H13."
所以我认为这个回复可以帮助您解决问题。
也有这个错误。不是由于超时，因为它会立即出现。我刚刚对 requirements.txt 进行了更改，包括更新了某些软件包的版本。当我在 Github 上时，我将 requirements.txt 文件回滚到以前的版本，这解决了问题。我的猜测是您的需求文件导致了问题（尽管很难将其中的特定行与错误隔离开来）。
运行 在尝试部署通过遵循 MDN Docs. Was able to resolve it by lowering the Django version to 2.2.10. Here is the requirements.txt file and the deployed app 创建的应用程序时遇到了同样的问题，因为它在本地工作。如果您不是专门出于某种目的使用 Django 3，那么将它降低到 2.2.10 应该没问题。 MDN 上的教程也是使用 django 2 制作的。
