构建 rShiny 应用程序后，我想在我自己的服务器上在线托管它。
我目前有一台带有 Ubuntu（最新版本）的服务器，我想在 Docker、Shinyproxy 和 nginx 的帮助下运行托管。
我已经创建了 Docker 映像并在“sudo docker run ....”的帮助下成功执行了它——这里一切正常。不幸的是，通过 ShinyProxy 托管不起作用。所以错误一定是（我认为）我的 ShinyProxy 文件（application.yml）或 nginx（默认，默认）。
当我调用 URL 时，我收到以下错误消息：（请参阅问题末尾的完整日志）
错误状态码：500 消息：容器未及时响应
我的 ShinyApp 通常由以下组件组成：Funktionen.R、Inputs.R、install_packages.R、Server.R、ui.R
我试图检查所有端口、设置和所有内容，但它不起作用。
我希望您找到分析以下错误所需的一切，并希望找到解决方案！非常感谢！
如果您需要更多信息，请告诉我！
