Following Steps will resolve "CORS Missing Allow Origin" Error for your Echo Server

STEP-1: Add "transports: ['websocket', 'polling', 'flashsocket'] // Fix CORS error." Code inside your Echo Server Setup File (public\js\laravel-echo-setup:js) like following code:

window.Echo = new Echo({
    broadcaster: 'socket.io',
    host: window.location.hostname + ':6001',
    transports: ['websocket', 'polling', 'flashsocket'] // Fix CORS error!
});

STEP-2: Build Your Code Using "npm run dev" command Restart your Laravel Echo Server Using "laravel-echo-server start" command Now check your application, You can't find a CORS error now.
