Ошибка winerror 10061

I’m debugging a simple program, that has worked in the past. I’ve singled out the instruction where the error takes place, but I cannot figure out what triggers it. I’ve read all questions related to WinError 10061, but I do not see a clear answer

I run Python 3 in Windows 8. I tried turning off the firewall, as a couple of people suggested, but nothing changes. I also tried to add Python to the list of Apps allowed by the firewall. By the way the program line worked without any problem until a few days ago, when I deleted a few Apps from my PC.

Всем привет, прошу помощи специалистов

Собрал свое первое приложение на Python с WEB интерфейсом Eel, затем скомпелировал в .exe файл при помощи Pyinstaller. На моем устройстве на Windows 10 все работает отлично, никаких проблем. Но на других компютерах, тоже Windows 10, вылазит следующая ошибка при попытке отправить запрос на Localhost

ConnectionRefusedError: [WinError 10061] Подключение не установлено, т.к. конечный компьютер отверг запрос на подключение

Подскажите пожалуйста, в чем может быть проблема и какие есть варианты решения?

I’m trying to send messages from one point to an other, it was working for a while, then when I went back home, it doesn’t work and I get this error:

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

The code for these are below. I even tried running it on a Mac and I got similar errors.

Client

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()

Server

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()

Any direction would be greatly appreciated!
