客户端刷新连接上的C#套接字错误代码10054

我一直在尝试为我正在构建的应用程序编写一个利用TCP的通信层。我控制服务器端和客户端操作

我遇到的问题是，当我使用“localhost”作为我的IP时，我没有任何问题。然而，当我使用互联网连接时，一切都会神奇地工作……第一次。当客户机尝试构建到服务器的另一个套接字连接时，我在ReadCallback期间，特别是在执行socket.EndReceive操作时，在服务器端得到SocketException错误代码10054

我已经看到了我的套接字没有得到正确处理的可能性——它们确实应该得到正确处理，因为我看不到客户端或服务器端应用程序的路径不会导致关闭
