[Python] i am getting [WinError 10022] An invalid argument was supplied. from my udp client...

I have two Python applications, client side and another server side.

client side:

import socket
import threading

UDP_IP = '127.0.0.1'
UDP_PORT = 56780

client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

nickname = input("Enter Nickname: ")
def write():
while True:
print("hello")
message = f"{nickname} -> {input()}"
client_socket.sendto(message.encode(), (UDP_IP, UDP_PORT))

def receive():
while True:
try:
message, _ = client_socket.recvfrom(1024)
print(message.decode())
except Exception as e:
print(e)
break


write_thread = threading.Thread(target=write)
write_thread.start()

receive_thread = threading.Thread(target=receive)
receive_thread.start()


server side:

import socket

HOST = '127.0.0.1'
PORT = 56780

server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
server_socket.bind((HOST, PORT))

clients = set()

def broadcast(message):
for client in clients:
server_socket.sendto(message, client)

def receive():
print("UDP Chat Server is running...")
while True:
try:
message, client_address = server_socket.recvfrom(1024)
if client_address not in clients:
clients.add(client_address)
print(f"Connected With {str(client_address)}")
broadcast(message)
except:
clients.remove(client_address)
receive()


The error I am having arises from the client side application, specifically from:

def receive():
while True:
try:
message, _ = client_socket.recvfrom(1024)
print(message.decode())
except Exception as e:
print(e)
break



The error is:

[WinError 10022] An invalid argument was supplied
​

This error only happens on my Windows system. On my Mac, the code seems to work exactly as it should.

I tried different ports to see if any of them worked, but it did not.

One thing I did detriment was that I get the error when I try to bind this part of the code to my server, but I can't figure out why and how to fix it.

message, _ = client_socket.recvfrom(1024)
