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:

Thanks everyone for answers. The problem was in ModSecurity, an Apache module that works as a web application firewall. I contacted hosting provider and they told be that was the issue.
If you are experiencing the same issue, check your server logs and provide them to your hosting provider to investigate if this is your issue.
