RStudio Server，Shiny 應用程序未啟動，應用程序頁面立即變灰

Question

Shiny 應用程序在更新包和 RStudio 服務器（shiny (1.3.2) 和 httpuv (1.5.1)）之前可以完美運行。 運行應用程序后，應用程序頁面立即變灰。

我已經嘗試過這個https://community.rstudio.com/t/shiny-v1-3-known-regressions-and-serious-issues/28180/4 ，但它仍然不起作用。 我也試過這個https://stackoverflow.com/a/27113322/10004051並且它有效，但我不想包含額外的代碼。

錯誤示例：

shiny::runExample("01_hello")

它適用於以下解決方法：

runExample("01_hello", host="0.0.0.0", port=9999)

這是我的會話信息：

此問題與 RServer 的代理配置錯誤有關，如下所述：

您必須使用以下文章作為指南更新您的代理配置：
