WCF传输安全性：套接字连接已中止

我在使运输安全工作方面遇到了问题 .

我有2个服务（A和B）在同一台服务器上运行 . 服务A将呼叫服务B执行某项任务 . 没有任何安全保障，我可以很好地沟通 . 但是当我使用以下设置打开传输安全性时：

• 安全模式=运输

• TransportClientCredentialType = Windows

• ProtectionLevel = EncryptAndSign

当服务A呼叫服务B时，我收到错误：

System.ServiceModel.CommunicationException：套接字连接已中止 . 这可能是由于处理消息的错误或远程主机超出接收超时或基础网络资源问题引起的 . 本地套接字超时为'00：00：09.7810000' . ---> System.IO.IOException：读取操作失败，请参阅内部异常 . ---> System.ServiceModel.CommunicationException：套接字连接已中止 . 这可能是由于处理消息的错误或远程主机超出接收超时或基础网络资源问题引起的 . 本地套接字超时为'00：00：09.7810000' . ---> System.Net.Sockets.SocketException：远程主机强行关闭现有连接

我尝试将接收和发送超时更改为5分钟但我仍然得到相同的错误，大致相同的超时持续时间 . 唯一的区别是我需要等待5分钟而不是1分钟 .

任何人都可以提供有关原因和解决方法的见解吗？

附件是两个服务的配置文件：
