Error: read ECONNRESET

[EbonyAdder]

I am attempting to use the gulp-vinyl-ftp plugin to upload to a remote site.

gulp.task("deploy", ["default"], function () {

    var conn = ftp.create({
        host: "mywebsite",
        user: "****",
        password: "******",
       // secure: true,
      timeOffset: -301,
       parallel: 1,
       debug: gutil.log
    });    

    var globs = [
        "distr/**/*.php",
        "!out/vendor/**",
        "!out/config.php",
        "out/**/*.map",
        "out/**/*.css",
        "out/**/*.js"
    ];
    return gulp.src(globs)
        .pipe(conn.newer("/")).pipe(debug({ title: "Deploy New: " }))
       // .pipe(conn.dest("/")).on("error", function (err) { console.log("Deploy Error: " + err); })

});

However, I am receiving the following error:

events.js:182
  throw er; // Unhandled 'error' event
  ^

Error: read ECONNRESET
    at exports._errnoException (util.js:1016:11)
    at TCP.onread (net.js:609:25)

The debug output is as follows:

    [08:37:28] [connection] < '220 Microsoft FTP Service\r\n'
[08:37:28] [parser] < '220 Microsoft FTP Service\r\n'

[08:37:29] [parser] Response: code=230, buffer='User logged in.'
[08:37:29] [connection] > 'FEAT'

It ends there.

However, I can connect just fine through WinSCP.

I have tried both the IP address and domain name in the host field, commenting out the the timeOffset and parallel options.

I am not sure where to go from here honestly; any advice would be appreciated.

Thanks.
