Laravel 5 SocketIO+；Redis连接已关闭

我遵循了提供的文档，服务器似乎不接受连接：

(failed)
net::ERR_CONNECTION_CLOSED

• 我正在使用Laravel Horizon，它似乎运行良好
• 如果我手动使用redis cli命令访问服务器 应用“ping”命令，我得到一个“pong”响应

应用laravel echo Server start命令后，服务器似乎已启动并运行：

L A R A V E L  E C H O  S E R V E R

version 1.3.6

⚠ Starting server in DEV mode...

✔  Running at localhost on port 6001
✔  Channels are ready.

Server ready!

bootstrap.js:

import Echo from 'laravel-echo'

window.io = require('socket.io-client');

window.Echo = new Echo({
    broadcaster: 'socket.io',
    host: window.location.hostname + ':6001',
});

你知道问题可能是什么，或者我可以从哪里开始寻找？我想这是一个配置问题，但我似乎无法指出问题所在。

对于其他遇到类似问题的人来说：原因是我的应用程序在本地使用https运行，而我没有将laravel echo server配置为这样做
