Laravel Echo, Redis, Socket IO and Laravel-echo-server stopped working and need ideas

Question

I'm having issues with getting laravel echo to work after moving to Ubuntu 20.04 on my production server. It use to work on 18.04. Both have the same Node version (my dev is v14). I'm wondering if anyone else is having issues or possible solutions. Btw, I tried switching to laravel-websockets and Soketi but those were a nightmare and I spent 3 days just trying to get them to connect (no luck).

In moving to Ubuntu 20.04, I updated package.json. I know there are issues with socket io and laravel-echo-server so those remained the same.

In the browser, there are no network errors. The socket io is reached. As well, nothing throwing an error in the console. Setting debug, I see the export event in Redis monitor and laravel-echo-server. However, Echo in the javascript never picks it up.

Would appreciate any feedback.

Answer 1

Added the port for the host and removed my Nginx config and now it's working.

import Echo from "laravel-echo"
window.io = require("socket.io-client");
window.Echo = new Echo({
    broadcaster: "socket.io",
    host: window.location.hostname + ':6001'
});
