我想将我的EC2实例作为一个服务器来监听我的本地机器，它是一个客户端 . 我在实例上运行server.py并运行并等待客户端，但在客户端，我收到此错误
“Traceback（最近一次调用最后一次）：文件”client.py“，第18行，在client_socket.connect（ADDR）文件”/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ socket.py“，第228行，在meth返回getattr（self._sock，name）（* args）socket.error：[Errno 60]操作超时”
这是我的双方代码：客户端
