IRC Bot Not Connecting Through Proxy Server in Python

Question

Introduce the Problem: I'm developing an IRC bot in Python that needs to connect to an IRC server through a proxy server. However, the bot fails to establish a connection.

Expand on the Problem: I am using the following modules: irc, socks, socket.

Terminal Output:

INFO:root:Bot created. Starting...

DEBUG:irc.client:connect(server='irc.libera.chat', port=6667, nickname='uwu', ...)

INFO:root:Successfully set proxy: 178.128.113.118:8000

DEBUG:irc.client:_dispatcher: disconnect

DEBUG:irc.client:process_forever(timeout=0.2)

Proxy: I am using a free proxy obtained from a website.

Expand on the Problem: Here is the relevant part of my code:

import irc.bot
import irc.strings
import irc.connection
import socks
import socket
import logging
import sys

logging.basicConfig(level=logging.DEBUG)

        if proxy_type:
            connect_factory = irc.connection.Factory(wrapper=self._get_wrapper)
        else:
            connect_factory = irc.connection.Factory()

                logging.info(f"Successfully set proxy: {self.proxy_addr}:{self.proxy_port}")
            except Exception as e:

        return sock

    def on_welcome(self, connection, event):
        logging.info(f"Connected to server. Joining channel {self.channel}")
        connection.join(self.channel)

    def on_join(self, connection, event):
        if event.source.nick == connection.get_nickname():
            logging.info(f"Joined channel {event.target}")
            connection.privmsg(self.channel, "hi guys")

def main():
    channel = "#Anime-18"
    nickname = "uwu"
    server = "irc.libera.chat"  # Using Libera Chat as it's a popular network

    proxy_type = socks.PROXY_TYPE_SOCKS4
    proxy_addr = "178.128.113.118"
    proxy_port = 8000

    try:
        bot = IRCBot(channel, nickname, server, port, proxy_type, proxy_addr, proxy_port)
        logging.info("Bot created. Starting...")
        bot.start()
