laravel websocket package is not connecting in laravel 5.8

I am using laravel websocket package instead of pusher . I have followed all the steps. server is also running when I connect it it gives these errors.

POST http://127.0.0.1:8000/auth 404 (Not Found)
GET http://127.0.0.1:8000/api/1234567/statistics

It is working fine with pusher but with this package it is creating issue
