4 years ago I think you must set the authEndpoint correctly. It must point to your backend and will return an auth token for pusher. So if I understood it correctly it goes like
-> echo client -> detects private-channel -> client makes post request for authentication to your backend -> backend returns auth token to client -> client connects with token to pusher
Set authEndpoint to "https://your.domain.org/broadcasting/auth" or localhost or whatever you are using.
