Lua / Love2D / LÖVE script not receiving IRC messages

Question

I've been trying to connect to Twitch chat IRC using Love2D. It manages to connect (if connect == 1 then). I'm just not sure how to receive any IRC messages that are being sent to me (love.update()).

function love.load()
    oauth = "oauth:someoauthhere"
    user = "botname"
    channel = "channeltojoin"

    love.graphics.setFont(love.graphics.newFont(32))

    socket = require("socket")
    irc = socket.tcp()
    connect = irc:connect("irc.chat.twitch.tv", 6667)
    if connect == 1 then -- MAKES IT PAST THIS
        irc_messages = {}
        irc:send("PASS " .. oauth)
        irc:send("USER " .. user)
        irc:send("JOIN #" .. channel)
    end
end

function update(dt)
    line, err = irc:receive() --> Returns nothing
    if line then
        table.insert(irc_messages, line)
    end
end

function love.draw()
    if not next(irc_messages) == nil then
        love.graphics.printf(table.concat(irc_messages, "\n"), 0, 0)
    end
end

Answer 1

I found a solution after spending a long time searching. Instead of this:
connect = irc:connect("irc.chat.twitch.tv", 6667)
I needed this:
connect = irc:connect(socket.dns.toip("irc.chat.twitch.tv"), 6667)
