Xamarin - FFImageLoading - System.IO.IOException

Question

我的XAML文件中有以下内容：

<ContentPage.Content>
<AbsoluteLayout HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
<StackLayout
AbsoluteLayout.LayoutFlags="All"
AbsoluteLayout.LayoutBounds="0,0,1,1">
<service:PinchPanContainer HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
<ffimageloading:CachedImage RetryCount="5" RetryDelay="1" CacheDuration="1" x:Name="MyImage" HorizontalOptions="Fill" VerticalOptions="CenterAndExpand" DownsampleToViewSize="False"></ffimageloading:CachedImage>
</service:PinchPanContainer>                
</StackLayout>
<StackLayout BindingContext="{x:Reference MyImage}" IsVisible="{Binding IsLoading}" Padding="12"
AbsoluteLayout.LayoutFlags="PositionProportional"
AbsoluteLayout.LayoutBounds="0.5,0.5,-1,-1">
<ActivityIndicator BindingContext="{x:Reference MyImage}" IsRunning="{Binding IsLoading}" />
<Label Text="Loading Hi-Res Image..." BindingContext="{x:Reference MyImage}" IsVisible="{Binding IsLoading}" HorizontalOptions="Center" TextColor="Black"/>
</StackLayout>
</AbsoluteLayout>
</ContentPage.Content>

并使用它来定义图像源：

MyImage.Source = uri;

Uri具有此值，并且图像在浏览器中正确加载：http://192.168.0.12/images/27kv4c1/2dbc5331/a08a31/IMG_4190-Modifica.png

但在模拟中，一旦我分配了源，我就会得到5倍的错误：

03-30 21:06:12.525 I/mono-stdout(28576): ---> (Inner Exception #5) System.IO.IOException: The server returned an invalid or unrecognized response.

可能是什么原因造成的？
