Homestead laravel real-time chat, private chat, no broadcast?

has recently been doing real-time push of messages, which was previously done with laravel"s pusher. Now I want to use redis+socket.io to do it. If it is stuck on the private channel, the public channel can be broadcast, but the private channel does not report an error, but it is not broadcast either, so I would like to ask if there is any great god who has done it to give me some advice?

got it out. I don't know why the demo on GitHub doesn't broadcast in my homestead and talk in private. Another project I worked on myself has been able to broadcast group chat and private chat. Tie up
