Errno111 连接被拒绝 Kivy 套接字错误

Question

I am a new beginner in kivy I am developing a app that connect to my windows pc using python sockets

This is my Kivy App code:

import kivy
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
import socket

class FloatLay(FloatLayout):
    def Connect(self):
        try:
            s = socket.socket()
            hostname = '127.0.0.1'
            port = 8080
            s.connect((hostname, port))
        except Exception as e:
            self.ids.text.text = str(e)


class MyApp(App):
    def build(self):
        return FloatLay()


if __name__ == "__main__":
    MyApp().run()

This is my.kv kivy file

<FloatLay>:
    Button:
        text:"Connect"
        pos_hint:{"x":0.6,"top":0.5}
        size_hint:0.1,0.05
        on_press: root.Connect()
    Label:
        id:text
        text:"Connect Status"
        pos_hint:{"x":0.2,"top":0.5}
        size_hint:0.4,0.05

This is my Socket_Server

import socket
def main():
 while True:
    running=False
    listensocket = socket.socket() 
    Port = 8080 
    maxConnections = 999
    IP = '127.0.0.1' #IP address of local machine
    listensocket.bind((IP,Port))
    listensocket.listen(maxConnections)
    print("Server started at " + IP + " on port " + str(Port))
    (clientsocket, address) = listensocket.accept()
    print("New connection made!")

    running = True
    try:
        while running:
            message = clientsocket.recv(1024).decode()
            print(message)
    except:
        print('')
main()

Whenever I run the code their is a error named Connection Refused

I dont think their is a mistake in my code as when i run the Client code and the Server on my windows pc at the same time they both are connected.

Note:I am running the App on a android device and the code on a windows pc

I have got the solution for this if you are using windows then follow these steps:

1. Open command prompt
2. Type ipconfig
3. Find the IPv4 in Wireless LAN adapter Wi-Fi section
4. Copy it and paste your IPv4 as a string to the IP vairable.

Note: Dont add any spaces while typing the IP
