Hey turds, what lib are you using to connect to the IRC? I’m using aiohttp and I check for aiohttp.WSMsgType.CLOSED to reconnect, when it comes to reconnecting Twitch expects you to wait exponentially for the reconnect to go through so I am using await asyncio.sleep(2 ** self.reconnections) to await before reconnecting.
Also not sure if this helps but the PONG reply to twitch PING should be sent as TEXT - at least it failed whenever I tried to use the aiohttp.websocket.pong.
Hope this helps
