System.ServiceModel.CommunicationException：TCP 错误（10049：请求的地址在其上下文中无效） 如何将 Azure 的 VM 用作服务器

问：

我正在尝试这样做，azure 的 VM 是我的服务器。 我在带有 WCF 的 Visual Studio 上使用 C#。 我的主机的app.config是：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <services>
      <service behaviorConfiguration="mexBehavior" name="TimbiricheService.UserManagerService">
        <endpoint address="UserManagerService" binding="netTcpBinding" 
                  bindingConfiguration="" contract="TimbiricheService.IUserManager" />
        <endpoint address="UserManagerService" binding="netTcpBinding" 
                  bindingConfiguration="" contract="TimbiricheService.IManagerOnlineUsers" />
        <host>
          <baseAddresses>
            <add baseAddress="http://20.81.133.87:8082" />
            <add baseAddress="net.tcp://20.81.133.87:8081" />
          </baseAddresses>
        </host>
      </service>
    </services>
</configuration>

我的 VM 具有以下规格：

和下一个规则

而且我已经停用了VM的防火墙

当我运行主机时，它会在 host.open（） 行上抛出下一个摘录;

namespace TimbiricheHost
{
    internal class Program
    {
        static void Main(string[] args)
        {
            using (ServiceHost host = new ServiceHost(typeof(TimbiricheService.UserManagerService)))
            {
                host.Open();
                Console.WriteLine("Server is running");
                Console.ReadLine();
            }
        }
    }
}

例外：

我该如何解决？

因为如果我把私有 IP 放在基址上，它就可以工作，但使用公共 IP 它就不起作用了

我已经禁用了防火墙，在 Azure 上添加了入站和出站端口的规则，以及我之前评论过的内容。
