WebSocket connection to 'wss://api.domain.com/parse/' failed:

Parse Server 📡
#1

Good day! It’s me again. I’m having trouble with my web-app project. Here is my Parse.Initialize block

var Parse = require('parse');
Parse.initialize("my-app-id");
Parse.serverURL = 'https://api.domain.com/parse/'

let LiveQueryClient = Parse.LiveQueryClient;
let client = new LiveQueryClient({
applicationId: 'my-app-id',
serverURL: 'wss://api.domain.com',
});

The project is currently live. But on the console of the browser, I am seeing a bunch of this log
WebSocket connection to 'wss://api.domain.com/parse/' failed .... LiveQueryClient.js:450

PS. The web socket is perfectly running on the mobile app.

Other Info
3 Parse Server App Instances
2 Load Balancers
1 Live Query Server

Is live query working in the client besides the error? If so, the client is probably loosing connection with the server time by time.
