Socket-io not working on Android with React Native and Expo

In my application I have implemented real time with socket-io with an external server (https://api.xxxxx.com:300)

Currently it works perfectly for iOS, but Android never gets to connect to the server.

On the server, socket io is declared as follows

var app = require('express')();
var fs = require('fs');
var options = {...};
var https = require('https').Server(options, app);
var io = require('socket.io')(https);
var curl = require('http');

io.on('connection', function(socket){
    ....
});

https.listen(3000, function(){
    console.log('listening on *:3000');
});

In my App.js File, I have to start the connection with the following code:

  // Initialize Socket IO:


global.socket = socketIO("https://api.xxxxx.com:3000", {
    transports: ['websocket'],
    forceNew: true,
    reconnectionDelay: 3000,
    reconnection: true,
    reconnectionAttempts: Infinity,
    jsonp: false
  });

  socket.connect();

  console.warn('First', JSON.stringify(socket['io']));

  socket.on('connect', () => {
    console.warn('Connect Correctly');
  });

  console.warn('Second', JSON.stringify(socket['io']));

As you can see, I print the state of the socket to see the readyStatus that at the moment First an Second always appears with readyStatus: "opening"

Later, I check the status of the socket in my application and a readyStatus: closed appears.

I remember that this only happens to me in Android, in iOS the operation is perfect and always ends with the connected state.

The versions that I have in my application are the following:
