I came from playcanvas.com from a project, need help loading the glitch server

Okay so, I forked a project that uses glitch to send and receive messages, I wanted to either use the code or see how it worked and update my own for player health and server siding more things like a scoreboard, but the link from the code won’t load a project. the link: https://playcanvas-mp.glitch.me/

var Network = pc.createScript('network');

Network.attributes.add('gamePlayManagerEntity', {type: 'entity'});

// static variables
Network.id = null;
Network.socket = null;

// initialize code called once per entity
Network.prototype.initialize = function() {
    // this.player = this.app.root.findByName('Player');
    // this.other = this.app.root.findByName('Other');
    this.player = this.gamePlayManagerEntity.script.gamePlayManagerScript.playerEntity;
    this.other = this.gamePlayManagerEntity.script.gamePlayManagerScript.otherEntity;
    // var socket = io.connect('https://playcanvas-multiplayer.glitch.me'); // Glitch hosted server
    var socket = io.connect('https://playcanvas-mp.glitch.me'); // Glitch hosted server
    Network.socket = socket;
    // socket.emit ('initialize');
    var nicknameVal = this.player.findByName('playerNickText').element.text;
    socket.emit ('initialize',{nicknameVal: nicknameVal});
    // this.displaySendMsg();

I think I will just set up my own node glitch server instead.
