Qt under Android QNetworkReply returns HostNotFoundError

Question

my goal is to run a php script and to GET the values returned. I work under Neccesitas SDK (Qt for Android) To do this I do:

m_NetworkAccessMNGR = new QNetworkAccessManager(this);
QEventLoop loop;
QNetworkReply* m_reply = m_NetworkAccessMNGR->get(QNetworkRequest(url));
connect(m_reply, SIGNAL(finished()),
        this, SLOT(slothttpFinished()));
connect(m_reply, SIGNAL(readyRead()),
        this, SLOT(slothttpReadyRead()));
connect(m_reply, SIGNAL(finished()), &loop, SLOT(quit()));
loop.exec();

ONLY on Android I get in this::slothttpReadyRead

m_reply->error() is QNetworkReply::HostNotFoundError

and m_reply->errorString() outputs:

ERROR: Host www.google.com not found

On Windows this works perfectly. Should I do some adaptations to Android? Maybe AndroidManifest.xml needs some setup made?
My AndroidManifest.xml contains, among others :

uses-permission android:name="android.permission.INTERNET"/>
uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Thank you
