ksoap2 подключение к web-сервису

Есть код:

   public class SrvConnectHelper extends AsyncTask< Void,Void,String> {
        private String host;
        private String username;
        private final String NAMESPACE = "http://www.nameorg.org";
        private final String SOAP_ACTION =NAMESPACE+"#exchange";
        public SrvConnectHelper(String host,String username){
            this.host = "http://"+host+":8080/LT/ws/exchange?wsdl";
            this.username = username;
        }
        @Override
        protected String doInBackground(Void... params) {
            SoapObject resultRequestSoap;
            SoapObject request = new SoapObject(NAMESPACE,
                    "getNomen");
            //SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(110);
            HttpTransportBasicAuth httpTransport = new HttpTransportBasicAuth(host,username,"");
            httpTransport.debug = true;
            try {
                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
                envelope.setOutputSoapObject(request);
                httpTransport.call(SOAP_ACTION, envelope);
                resultRequestSoap = (SoapObject) envelope.getResponse();
                return resultRequestSoap.toString();
            } catch (XmlPullParserException e) {
                e.printStackTrace();
                return "Unable to read XML: "+e.toString();
            }catch (IOException e){
                e.printStackTrace();
                return "Unable to read XML: "+e.toString();
            }
        }
    }

Есть web-сервис, который опубликован средствами 1с, имя сервиса "exchange", пространство имен "http://www.nameorg.org". Проблема в том, что приложение вылетает на этой строке:

httpTransport.call(SOAP_ACTION, envelope);

Думаю неправильно задал SOAP_ACTION, как исправить ошибку?

Вот кстати логи:
