C# Csharp命名管道服务器连接问题

我在远程计算机上有一个服务器，当我连接到管道时，它将不允许我连接，直到我在服务器端重新启动计算机。随机测试可能会在几周后进行。我将max-instance属性放在服务器端。有什么想法吗？我还检查了前一个连接是否已关闭，并且似乎已关闭，因为我在客户端显示了实例数。下面是用于服务器端的代码

public void ProcessNextClientServiceApp()
{
            ps = new PipeSecurity();
            ps.AddAccessRule(new PipeAccessRule("Users", PipeAccessRights.ReadWrite | PipeAccessRights.CreateNewInstance, AccessControlType.Allow));
            ps.AddAccessRule(new PipeAccessRule("CREATOR OWNER", PipeAccessRights.FullControl, AccessControlType.Allow));
            ps.AddAccessRule(new PipeAccessRule("SYSTEM", PipeAccessRights.FullControl, AccessControlType.Allow));
            pipeStream = new NamedPipeServerStream(PipeName, PipeDirection.InOut, NamedPipeServerStream.MaxAllowedServerInstances, PipeTransmissionMode.Message, PipeOptions.None, 1024, 1024, ps);
                Console.WriteLine("Waiting...");
                pipeStream.WaitForConnection();

                PassClient(pipeStream);
    }


    public void PassClient(NamedPipeServerStream pipeStream)
    {
        var thread = new Thread(() =>
        {
                while (pipeStream.IsConnected){}

            CloseNamedPipe();
            
        });
        thread.IsBackground = true;
        thread.Start();
    }
