Shows err connection time out while running socket.io

While I serve the app it shows "GET http://114.134.90.66:8080/socket.io/?EIO=3&transport=polling&t=Lu3RCzm net::ERR_CONNECTION_TIMED_OUT "

import {NavController,NavParams} from 'ionic-angular';
import { Component,ViewChild } from '@angular/core';
import {ShowActionSheet} from '../../components/show-action-sheet/show-action-sheet.component';
import * as io from "socket.io-client";

@Component({
  templateUrl: 'chat.html'
})

export class ChatPage {
  socket: SocketIOClient.Socket;
  params: any;
  chatBox:any;
  messages:Array<any>=[];
  name:any;
  @ViewChild(ShowActionSheet)
  private showActionSheet: ShowActionSheet;
  constructor(public nav: NavController, public navParams: NavParams) {
    this.params = navParams;
    this.name = this.params.get('name');

  }




  presentActionSheet(actionSheetType) {
    this.showActionSheet.presentActionSheet(actionSheetType);
    
  }
  private send(text){
 
    this.connect();
      this.chatBox=text;
      this.messages.push(this.chatBox);
      this.chatBox='';


  }
  connect() {
    this.socket=io('http://114.134.90.66:8080');
    this.socket.on('connect', function () {
        
        console.log("SOCKET CONNECTED");
    });
}





}

I have no idea why isn’t it working. I have successfully installed typings.

How and where are you testing?
Is the IP/site accessible in the normal OS browser?
What is your ionic info output?
