我正在尝试为 Windows 发布一个独立的可执行文件。当我尝试通过特权 powershell（或 cmd）窗口运行可执行文件时，我收到以下错误：

Unhandled exception. System.AggregateException: One or more errors occurred. (No connection could be made because the target machine actively refused it.)
 ---> System.Net.Http.HttpRequestException: No connection could be made because the target machine actively refused it.

如果它是相关的，在那条线上，我正在连接到另一台机器上的 tomcat 托管服务器。

奇怪的是，当我发布非独立应用程序时，我没有收到错误消息。应用程序成功运行完成。当我在 Visual Studio 中以调试模式运行程序时，我也没有收到错误消息。此外，我为 linux-x64 构建了一个独立的可执行文件，并且能够在 linux 机器上成功运行。

我尝试禁用 Windows Defender 防火墙和类似程序。但是，由于程序在其他情况下运行良好，我认为这不是防火墙问题。

独立的可执行文件有问题吗？在 Windows 上运行自包含的可执行文件之前，我是否遗漏了什么？我不知道如何解决这个问题。
