Submitting larger images with Ajax Jquery to Laravel Controller

I'm trying to upload images to the database using Ajax Jquery.It works fine for small files (less than 100kb) and gets uploaded to the database. I have changed the php.ini for file uploading limits(upload_max_filesize = 40M) and post upload limits to 40M(post_max_size = 41M) and tried to upload an image with 300kb but still nothing. When i click on console, i see "No response data".

Controller

  public function store(Request $request)
{

   // ($request->all());
    $formInput=$request->except('filename');

    $product = product::create(array_merge($formInput, [
        'seller_id'=> Auth::user()->id,
        'user_id' => Auth::user()->id
    ]));
    foreach ($request->photos as $photo) {
       $filename = $photo->store('public/photos');
        ProductsPhoto::create([
            'product_id' => $product->id,
            'filename' => $filename
        ]);
    }

}

Ajax

var token = $("#token").val();
$(document).ready(function(){
$("#btn").click(function(){
    var url = '';
    var form = $('form')[0]; 
    var formData = new FormData(form);
    formData.append('_token', token); // adding token
    $.ajax({
        url: url,
        data: formData, 
        type: 'POST',
        contentType: false,
        processData: false, 
        success:function(data){
         console.log(data);
        }
    });
  });
});
