Bug? I have a problem with HttpUtils2, on b4i it works fine, but on b4a it fails.

Sub sumandopub   
    Dim datos,cadena As String
    Dim j As HttpJob   
    idcel="0"
    sversion="nada"
    idpub="nada"
    xtipopub="android"   
    cadena="https://www.siracmexico.com/movilprod/siguientevisto.php/?xid="&idpub&"&xsiglas="&radio&"&xcel="&idcel&"&xversion="&sversion&"&xtipovia="&xtipopub
    'https://www.siracmexico.com/movilprod/siguientevisto.php/?xid=nada&xsiglas=XHSK&xcel=0&xversion=nada&xtipovia=android
    Log(cadena)
    j.initialize("",Me)
    j.Download(cadena)
    Wait for (j) JobDone(j As HttpJob)
    If j.Success Then
        datos=j.GetString
        Log(datos)
        Log("publicidad registrada")
    Else
        Log("falla publicidad")
    End If       
End Sub
