SSL connection timeout, iOS

[bushev]

Hello, Enrico!

First of all, I want to thank you for supporting this awesome project! It can really help to build a mobile application for NodeJS developers.

I having a trouble to connect to a MongoDB with SSL using an official driver.

The problem: My code works fine in a PC environment, but don't on jxcore (timeout error).

Platform: iOS (10)
Cordova CLI : 7.0.1
Xcode: 8.3.3

const mongodb     = require('mongodb');
const MongoClient = require('mongodb').MongoClient;

const url = `mongodb://testUser:123456@aws-us-east-1-portal.28.dblayer.com:23087,aws-us-east-1-portal.29.dblayer.com:23087/admin?ssl=true`;

MongoClient.connect(url, {
    loggerLevel: 'debug',
}, (err, db) => {
    if (err) return console.log(err);

    console.log('Connected correctly to server');

    db.admin().listDatabases().then((databases) => {
        console.log(databases);
    }).catch(err => {
        console.log(err);
    });
});

I got a timeout error:

UPD

Just updated OpenSSL to latest (1.0.2l) - unfortunately, the result is the same.

It seems on data event is never emitted on a tls socket.

UPD2

After deep investigation, I have found that problem was solved in iojs 3.0.0

UPD3
The same for SpiderMonkey build.

@enricogior, how realistic to fix TLS connection?

[enricogior]

Hi @bushev
sorry for the late reply, I've been very busy.
First of all, thank you very much for opening the issue.
When you said that you found the problem solved in iojs 3.0.0, to which commit are you referring?
Thank you.
