Intermittent image loading issue. Especially on a slower network. Can someone here possibly help or give ideas on a workaround ?

Description

I am using Xamarin to create a eCommerce mobile app that uses shopify as backend. I use syncfusion for most of my controls. However for some reason not all images are always displaying. Sometimes all the images display, sometimes none display.

I am using: XF: v4.0.0.8055-pre1 FFImage: V2.4.5.860-pre

Below is my xaml

<ffimageloading:CachedImage LoadingPlaceholder=“https://reactnativecode.com/wp-content/uploads/2018/02/Default_Image_Thumbnail.png” Source=“{Binding images[0].src}” Aspect=“AspectFit” />

I have noticed when I am on a really fast internet connection all my images load. Otherwise sometimes only one or two load. Could shopify be causing a forbidden if ping is below a certain level.

Below is the console error I am receiving and can see its getting a forbidden but when I access the image directly on a browser it works: Image loading failed: https://cdn.shopify.com/s/files/1/0266/8563/products/Coinfy_Tilt_Table_3_web.jpg?v=1545382216 01-03 13:56:14.012 I/mono-stdout(15349): Image loading failed: https://cdn.shopify.com/s/files/1/0266/8563/products/Coinfy_Tilt_Table_3_web.jpg?v=1545382216 FFImageLoading.DownloadAggregateException: One or more errors occurred. —> System.Net.Http.HttpRequestException: Forbidden at FFImageLoading.Cache.DownloadCache+<DownloadAsync>d__17.MoveNext () [0x002c7] in C:\projects\ffimageloading\source\FFImageLoading.Common\Cache\DownloadCache.cs:123 — End of stack trace from previous location where exception was thrown — at FFImageLoading.Cache.DownloadCache+<>c__DisplayClass16_0+<<DownloadAndCacheIfNeededAsync>b__0>d.MoveNext () [0x00050] in C:\projects\ffimageloading\source\FFImageLoading.Common\Cache\DownloadCache.cs:59 — End of stack trace from previous location where exception was thrown — at FFImageLoading.Retry+<DoAsync>d__01[T].MoveNext () [0x00047] in C:\projects\ffimageloading\source\FFImageLoading.Common\Helpers\Retry.cs:18 01-03 13:56:14.014 I/mono-stdout(15349): FFImageLoading.DownloadAggregateException: One or more errors occurred. ---> System.Net.Http.HttpRequestException: Forbidden --- End of inner exception stack trace --- at FFImageLoading.Retry+<DoAsync>d__01[T].MoveNext () [0x0015b] in C:\projects\ffimageloading\source\FFImageLoading.Common\Helpers\Retry.cs:32 — End of stack trace from previous location where exception was thrown — 01-03 13:56:14.014 I/mono-stdout(15349): at FFImageLoading.Cache.DownloadCache+<DownloadAsync>d__17.MoveNext () [0x002c7] in C:\projects\ffimageloading\source\FFImageLoading.Common\Cache\DownloadCache.cs:123 at FFImageLoading.Cache.DownloadCache+<DownloadAndCacheIfNeededAsync>d__16.MoveNext () [0x00413] in C:\projects\ffimageloading\source\FFImageLoading.Common\Cache\DownloadCache.cs:58 01-03 13:56:14.015 I/mono-stdout(15349): — End of stack trace from previous location where exception was thrown — — End of stack trace from previous location where exception was thrown — at FFImageLoading.DataResolvers.UrlDataResolver+<Resolve>d__7.MoveNext () [0x00045] in C:\projects\ffimageloading\source\FFImageLoading.Common\DataResolvers\UrlDataResolver.cs:24 — End of stack trace from previous location where exception was thrown — at FFImageLoading.DataResolvers.WrappedDataResolver+<Resolve>d__2.MoveNext () [0x00044] in C:\projects\ffimageloading\source\FFImageLoading.Common\DataResolvers\WrappedDataResolver.cs:22 01-03 13:56:14.016 I/mono-stdout(15349): at FFImageLoading.Cache.DownloadCache+<>c__DisplayClass16_0+<<DownloadAndCacheIfNeededAsync>b__0>d.MoveNext () [0x00050] in C:\projects\ffimageloading\source\FFImageLoading.Common\Cache\DownloadCache.cs:59 — End of stack trace from previous location where exception was thrown — at FFImageLoading.Work.ImageLoaderTask3+<RunAsync>d__109[TDecoderContainer,TImageContainer,TImageView].MoveNext () [0x00300] in C:\projects\ffimageloading\source\FFImageLoading.Common\Work\ImageLoaderTask.cs:561 ---> (Inner Exception #0) System.Net.Http.HttpRequestException: Forbidden at FFImageLoading.Cache.DownloadCache+<DownloadAsync>d__17.MoveNext () [0x002c7] in C:\projects\ffimageloading\source\FFImageLoading.Common\Cache\DownloadCache.cs:123 --- End of stack trace from previous location where exception was thrown --- at FFImageLoading.Cache.DownloadCache+<>c__DisplayClass16_0+<<DownloadAndCacheIfNeededAsync>b__0>d.MoveNext () [0x00050] in C:\projects\ffimageloading\source\FFImageLoading.Common\Cache\DownloadCache.cs:59 --- End of stack trace from previous location where exception was thrown --- at FFImageLoading.Retry+<DoAsync>d__01[T].MoveNext () [0x00047] in C:\projects\ffimageloading\source\FFImageLoading.Commo n\Helpers\Retry.cs:18 <—

We are running into the same issue but @edwinjeppe1’s above fix is not helping, there seems to be a number of scattered reports of this but no resolution @daniel-luberda has there been any investigation into this?
