How can I correct an 'only one socket usage of each address error' caused by a process being spawned within a class?

Question

Currently, I am trying to develop a server framework which passes messages from twitch to other machines on a local network. I have a class called server and below I have a rudimentary example which demonstrates the problem I am running into. The issue is that the twitch_socket is being created twice and bound to the address/port. My expected result is that the socket would be shared between the child processes of the Server class. How can I modify the class, or even get rid of it entirely, so that the Processes would be able to share sockets between them?

import multiprocessing
import socket
import re
from BotPass import PASSWORD
def send_message(socketobj, message):
    'Sends a str as bytes through socket'
     message = message.encode()
     socketobj.sendall(message)
def recv_message(socketobj):
    'Receives a str as bytes though socket'
    return socketobj.recv(2048).decode()
class Server:
    'Handles receiving messages from twitch and directs messages from clients'
    twitch_socket = socket.socket()
    twitch_socket.connect(('irc.chat.twitch.tv', 6667))
    send_message(twitch_socket, 'PASS %s\r\n' % (PASSWORD))
    send_message(twitch_socket, 'NICK %s\r\n' % ('squid_coin_bot'))
    send_message(twitch_socket, 'JOIN #jtv\r\n')
    send_message(twitch_socket, 'CAP REQ :twitch.tv/commands\r\n')
    server_socket = socket.socket()
    server_socket.bind(('', 9999))
    work_queue = multiprocessing.Queue()
    #Queue of messages from twitch
    worker_queue = multiprocessing.Queue()
    #Queue of free client socket objects
    result_queue = multiprocessing.Queue()
    #Queue of what to send back to twitch
    def start():
        accept_process = multiprocessing.Process(target=Server.accept_connections)
        # *This is most likely where the issue is occurring*
        accept_process.daemon = True
        accept_process.start()
    def accept_connections():
         ''
        Server.server_socket.listen(10)
        while 1:
            (clientsocket, clientaddr) = Server.server_socket.accept()
            # What I believe I am referencing here is the server socket which is inherent to the Server class
            if re.match(r'192\.168\.\d{1,3}\.\d{1,3}', clientaddr[0])\
             or clientaddr[0] == '127.0.0.1':
                Server.worker_queue.put(clientsocket)
            else:
                clientsocket.close()
Server.start()
input()

Output in Console:

Add this socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) This is because the previous execution has left the socket in a TIME_WAIT state, and can’t be immediately reused.the SO_REUSEADDR flag tells the kernel to reuse a local socket in TIME_WAIT state, without waiting for its natural timeout to expire.
