Xamarin UITest REPL 树“无法连接”

问题描述

我有一个带有 UITests 的 Xamarin Android 应用程序。这些测试对我团队的其他成员运行良好，但对我来说总是失败。我收到这条消息：

System.Exception : Error while performing Query(Marked("edtLogin"))
      ----> System.Net.Http.HttpRequestException : An error occurred while sending the request.
      ----> System.Net.WebException : Unable to connect to the Remote Server
      ----> System.Net.sockets.socketException : No connection Could be made because the target machine actively refused it 127.0.0.1:60757

如果我在此之前尝试做一个 repl 树，我会得到同样的错误。我在硬件上运行（没有模拟器）。在 2 台设备上尝试了相同的结果（Zebra TC75 和三星 S9+）
