Downloading multiple file from ftp site using node js - node.js

Question

i am trying to download each file on ftp server from root folder.
what i did is this-
ftpClient.ls(".", function(err, res) {
res.forEach(function(file) {
console.log(file.name);
ftpClient.get("./"+file.name, 'D:/styleinc/ftp/'+file.name, function(hadErr) {
if (hadErr)
console.log(hadErr);
else
console.log('File copied successfully!');
});
});
but on running it gives me error-
{ [Error: connect ECONNREFUSED]
code: 'ECONNREFUSED',
errno: 'ECONNREFUSED',
syscall: 'connect',
msg: 'Probably trying a PASV operation while one is in progress'
}
i have already successfully logged in and authenticated my self on ftp site.....
i don't know what to do please guide me.

This is the chunk of code I used with async.mapLimit to make it work with only one connection concurrently.
'use strict'
var JSFtp = require('jsftp');
var inspect = require('util').inspect;
var fs = require('fs');
var async = require('async');
var ftp = new JSFtp(require('./util/ftp'))
var local = 'EDI/mohawk/OUTBOX/'
var remote = 'OUTBOX'
var gatherFiles = function(dir){
return new Promise(function(resolve, reject){
ftp.ls(dir + '/*', function(err, res) {
if (err) reject(err)
console.log(res)
var files = [];
res.forEach(function(file){
files.push(file.name)
});
resolve(files)
})
})
}
gatherFiles(remote).then(function(files){
console.log(files)
async.mapLimit(files, 1, function(file, callback){
console.log('attempting: ' +remote + file + '->' + local + file)
ftp.get(remote +'/'+ file, local +'/'+ file, function(err){
if(err){
console.log('Error getting ' + file)
callback(err)
}else{
console.log('Got ' + file)
callback()
}
})
}, function(err, res){
if(err){
console.log(err)
}
console.log('updates complete' + res)
})
})
