部分（但不是全部）由 nginx 代理的静态内容成功加载

Question

我在 Windows 机器上设置了 nginx 作为反向代理，通过 SSL 监听 443。当我访问某个特定的 URL 时，它应该为我在本地运行的 node js web 应用程序提供服务。它成功访问了该应用程序 - 但是，它加载了部分但不是全部的 web 应用程序静态内容。哪个每次文件未加载的情况都不同。

有几个 css 和 JavaScript 文件需要加载。当我检查 Chrome 中开发者工具的网络选项卡时，它显示两个文件无限期挂起，而其他文件已加载正常。哪两个文件有所不同每个时间。

这是我的 nginx.conf（为了保护隐私，我替换了实际的 URL）：

    worker_connections  1024;

我已将 nginx 错误日志设置为调试，并在此处包含了（希望）相关的部分。可能发生了某种类型的 ssl 读取错误。

我对 nginx 还很陌生，请对我宽容一点。:)
