connectionrefuederror:[WinError 10061]无法建立连接，因为目标计算机主动拒绝了

Question

我试着从一个点到另一个点发送消息，它工作了一段时间，然后当我回到家，它不工作，我得到这个错误：

line 20, in connect
    self.mySocket.connect((self.serverName, self.serverPort))
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

代码如下。我甚至试着在Mac上运行它，结果也出现了类似的错误。

客户

import socket

    serverName = "my_IP_Address"
    serverPort = 12000

    class User:
        mySocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

        def __init__(self):
            self.serverName = serverName
            self.serverPort = serverPort

        def connect(self):
            print("Trying to connect at " + str(self.serverName) + " on port " + str(self.serverPort))
            self.mySocket.connect((self.serverName, self.serverPort))

        def sendMessage(self, msg):
            newS = msg.encode('utf-8')
            self.mySocket.send(newS)
            modifiedData = self.mySocket.recv(2048)

        def closeSocket(self):
            self.mySocket.close()

        def listen(self):
            self.mySocket.bind(('', self.serverPort))
            self.mySocket.listen(1)
            print("We are ready to receive data on port " + str(serverPort))
            while (1):
                print("** attempting ** ")
                connectionSocket, addr = self.mySocket.accept()
                rcvMsg = connectionSocket.recv(2048)
                newMsg = "I have received: " + rcvMsg.decode('utf-8')
                print(newMsg)
                newMsg = newMsg.encode('utf-8')
                connectionSocket.send(newMsg)
                connectionSocket.close()

                if (rcvMsg.decode('utf-8') == 'done'):
                    break
            print("done listening")

    def main():
        userA = User()
        userA.listen()

    main()

服务器

def main():
    userA = User()
    userA.connect()
    msg = "Hello from the lab"
    while(msg != "done"):
        userA.sendMessage(msg)
        msg = input("please type another message to send: ")
    print("done transmitting messages")


main()

任何方向都将不胜感激！

我发送了太多请求，而我的ISP阻止了我的请求（因此它拒绝了连接）。一旦我搬到了一个新的网络，我就可以让它重新工作。
