当Debug = False时，Django App总是返回404

Question

我正在尝试部署一个django应用程序，它基本上是我服务器中托管的readthedocs实例。根据文档建议，它配置了gunicorn + nginx，但我发现了一个小问题：无论我在URL中输入什么，应用程序始终都会返回404错误。我尝试了一些实验，我发现如果我在DEBUG = True设置settings.py，那么一切正常。我找不到任何能够提供相关信息的日志文件，到目前为止我搜索的所有内容都说明问题通常在于静态文件，而不是模块。我的问题在于整个模块。

如何查看该应用有什么问题？我应该从哪里开始？

这是相关的配置文件：
