Python IRC bot for Twitch authentication error

Hey everyone, I need help with a Twitch bot issue.

I’m working with Python 2.7 and trying to build an IRC bot for Twitch streaming. The weird thing is that I got my bot working fine on other IRC networks like freenode, but Twitch is giving me problems.

Here’s my current code:

import socket
import time

SERVER = "irc.twitch.tv"
PORT_NUM = 6667
BOT_NAME = "chatbot"
OAUTH_TOKEN = "oauth:abc123xyz789token456here"
CHANNEL = "#streamername"

connection = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
connection.connect((SERVER, PORT_NUM))
connection.setblocking(False)
time.sleep(1)

connection.send("PASS "+OAUTH_TOKEN+"\r\n")
time.sleep(1)
connection.send("USER "+BOT_NAME+" "+BOT_NAME+" "+BOT_NAME+" :Bot Here!\r\n")
time.sleep(1)
connection.send("NICK "+BOT_NAME+"\r\n")
time.sleep(1)
connection.send("JOIN "+CHANNEL+"\r\n")

response = ""
while True:
    try:
        response = connection.recv(1024)
        print response
    except:
        continue
    if "PING" in response:
        connection.send("PONG "+response.split()[1]+"\r\n")

But I keep getting this error message:

:tmi.twitch.tv NOTICE * :Login authentication failed

Anyone know what I’m doing wrong here? The OAuth token should be correct but maybe I’m missing something in the connection process?

check ur oauth token for weird characters or trailing spaces. i had this exact problem - turned out i copied an invisible character when i grabbed the token from twitch. also make sure u logged into ur bot account in the browser at least once before connecting to irc.

Had this exact problem building my Twitch bot last year. You’re using an outdated OAuth token method. Get your token from Twitchapps TMI Token Generator - RIP or the official Twitch developer console - don’t use those old third-party generators. Also, your bot username has to match the Twitch account that generated the OAuth token exactly. Case sensitivity matters. Since you’re on Python 2.7, you’ll probably hit encoding issues with socket operations. Add .encode(‘utf-8’) to your connection.send() calls.

I encountered a similar authentication error with my Twitch bot recently. Typically, this issue arises from either the OAuth token format or the timing of the commands. Ensure that your token begins with ‘oauth:’ and does not contain any extra spaces or unusual characters. Timing is crucial as well; consider introducing a brief pause after sending the PASS command before proceeding with USER and NICK. It is also important to log into the bot account via the web at least once and verify that your token has the necessary chat permissions. If you are still experiencing issues, I recommend regenerating the token in the Twitch developer console.

Your authentication command order caught my eye - Twitch IRC is picky about this. You need to send PASS, then NICK, then USER. Standard IRC networks don’t care as much, but Twitch does. Also check that your OAuth token was generated for chat bots from the Twitch dev console with the right scopes. Tokens can expire or go invalid if you don’t use them quickly enough. I’d regenerate a fresh token and fix that command sequence. Your timing delays look fine, but the order matters way more than you’d think with Twitch’s setup.
