Use HttpClient in Maui

Question

When I use HttpClient in MauiApp. It works well in the Emulator, but not on the mobile phone, Why is that?(android) its a bug(?

 private void OnCounterClicked(object sender, EventArgs e)
        {
//            HttpClient httpClent = CreateHttpClient();
//#if __ANDROID__
//                        httpClent = new HttpClient(new Xamarin.Android.Net.AndroidMessageHandler());
//#endif

            HttpClient httpClent = new();
            var res = httpClent.GetAsync($"https://xxxx.xxx/Image/Pochama/pocha-{count}.jpg");
            //PokeImg.Source = ImageSource.FromStream(() => new MemoryStream(res.Content.ReadAsByteArrayAsync().Result));

            //File.WriteAllBytes($"{count}.png", res.Content.ReadAsByteArrayAsync().Result);
            //var stream1 = new MemoryStream(imageAsBytes);
            //PokeImg.Source = $"pocha_{count % 88}.png";
            count++;
            CounterLabel.Text = $"Current count: {count}";

            SemanticScreenReader.Announce(CounterLabel.Text);
        }
