Titanium SDK 3.3.0 Http Error?

Hey,

i am using Kinvey as a backend and trying to make a "normal" http call to them:

var xhr = Ti.Network.createHTTPClient({
        onload: function(e) {
            console.log(this.responseText);
            alert('success');
        },
        onerror: function(e) {
            // this function is called when an error occurs, including a timeout
            console.log(e);
            alert('error');
        },
    });
 
    xhr.open("POST", Kinvey.API_ENDPOINT + '/push/kid_XXXXXXX/register-device');
    xhr.setRequestHeader('Authorization', 'Kinvey ' + Kinvey.getActiveUser()._kmd.authtoken);
    xhr.setRequestHeader('Content-Type', 'application/json');
 
    console.log("Token: " + token);
    xhr.send({
        'platform' : 'ios',
        'deviceId' : token
    });

I don't know why, but since the newest SDK this results in a http error - regardless what i am trying to do. I saw in the release notes that something was changed at the http and ssl stuff in titanium.

But i can't figure out what - Does anybody know if i have to adjust something to get this work? (The url is a secured connection of course)

If i paste the url in the browser everything is fine - so i think it's a titanium problem.

Help would be really great.

Best, Nico
