I am using Volley to upload pictures from Android application to server. In case when I have more than 3 pictures for upload, Volley throws AuthFailureError, even though I don't use any kind of authentication. For each picture, I am using separate request, which is sent when I receive response for previous one. Here is a code. Does anyone know what is the problem? Or shall I simply switch to Retrofit? Thanks!
private void sendRequest(String control){
Toast.makeText(MainReviewActivity.this, control, Toast.LENGTH_LONG).show();
//Toast.makeText(AfterLoginActivity.this, control, Toast.LENGTH_LONG).show();
StringRequest stringRequest = new StringRequest(Request.Method.POST, UploadUrl, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
waiting_search_results = 0;
JSONObject jsonObject = new JSONObject(response);
String Response = jsonObject.getString("response");
if (control.equals("review_page_restaurant_search") || control.equals("review_page_meal_search")){
prepareSearchResultDataFromServer(control, Response);
} else{
if (control.equals("review_page_perform_review")){
if (Response.equals("Success")){
// check if there are pics to send
Log.d("debug:", "Perform review - positive resp received");
enablePicSending = 1;
} else{

EDIT I read more about Authentication failure and I noticed in documentation that when that happens, server shall provide WWW-Authenticate response header, so I tried to read it with parseNetworkResponse function. In the moment of Toasting (i.e. the moment after parsing the latest network response), my observations are following: WWW-Authenticate header is missing, some pictures are not uploaded to server, server provided response 200, but Volley called onErrorResponse method (from which I am Toasting). How is it possible to receive response 200, but AuthFailureError is detected in OnErrorResponse method? New code, with parsing network response and debug Toasts:

prepareSearchResultDataFromServer(control, Response);
