EPROTO 140502679459712:error:1408F10B:SSL routines:ssl3_get_record:wrong version number- Response not received - no connection was made to the service.

Hi,

we have done the migration of Watson service and the consequent update of the library ibm-watson.

After the update our script doesn't work properly and returns the following error:

{ Error: write EPROTO 140502679459712:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:252:

statusText: 'EPROTO',
body:
'Response not received - no connection was made to the service.' }

To understand if the problem was inherent with the environment, we have tried the following simple code, but returns the same error:

var DiscoveryV1 = require('ibm-watson/discovery/v1');
const { IamAuthenticator } = require('ibm-watson/auth');

const discovery = new DiscoveryV1({
    version: '2019-04-30',
    authenticator: new IamAuthenticator({
        apikey: '*************',
    }),
    url: '*************'
});

discovery.getCollection({
    environmentId: "********",
    collectionId: "********",
}).then(collection => {
    console.log('collection', collection)
}).catch(err => {
    console.log('---------------- ERROR GETCOLLECTION:', err)
})

We have tried the same code in local and works properly.

Another test done consists in the use of request library on the VM. Following the code:

const request = require('request');

var env = "********";
var col = "********";
var document_id = "1234"

request.get(`https://gateway-fra.watsonplatform.net/discovery/api/v1/environments/${env}/collections/${col}/documents/${document_id}`, {
    qs: {
        version: '2019-04-30'
    },
    auth: {
        user: 'apikey',
        pass: '************',
        sendImmediately: false
    },
    json: true
}, function (err, data) {
    if(err){
        console.log('err', err)
    }else{
        console.log('data',data)
    }
});

We have done the same test with Axios library and it works properly on the VM:

const axios = require("axios")

var environment_id = "**********";
var collection_id = "***********";
const {
    IamAuthenticator
} = require('ibm-watson/auth');

async function run() {
    try {
        let response = await axios({
            url: `https://gateway-fra.watsonplatform.net/discovery/api/v1/enviro                                                                                                                                                                                                nments/${environment_id}/collections/${collection_id}?version=2019-04-30`,
            auth: {
                username: 'apikey',
                password: '************'
            },
        })
        console.log(response.data);
    } catch (e) {
        console.log(e.message)
    }
}

run()

Request and Axios library work properly on the VM.
So from this tests, we think that the problem is between the setting on the VM and the ibm-watson library.

Following some info of the VM where we run the code:
