毕加索加载图片失败

Question

i want to load images by picasso. i use this code

    Picasso.with(getContext())
    .load("https:/url.com")// here you resize your image to whatever width and height you like

    .into(imghotel, new Callback() {
        @Override
        public void onSuccess() {

        }

        @Override
        public void onError() {
            Toast.makeText(getContext(), "error", Toast.LENGTH_SHORT).show();
        }
    });

there is one big problem that i cant handle it. when i test another url all thing is ok. when i test this url by android 23 and 26 all thing is ok. but when i test this url by android 19 picasso dont show image and show gateway timeout error .

i think ther is some problem in my php server.
