That looks perfectly normal to me, except that Twitch didn’t respond to your CAP REQ command because your bot already joined a chatroom. You should send any CAP REQ commands right after connecting and before joining any channel, otherwise it won’t work.
And is the chatroom you’re trying to join a very active one? If not, then try sending a message in that same channel, preferably with a different username. If you can see them in your bot’s console window, then you’re good to go.
