SOLVED: poster and backdrop not loading in details page

[phynias]

for some reason the poster and backdrop are not loading in just the details page just in a web browser (works in apps).
the posters are fine in the main listing pages. 
when i edit the images i can see a primary and backdrop set.


the only errors i see in the logs are when i do a scan and i see

  at Emby.Server.Implementations.Library.LibraryManager.ConvertImageToLocal(BaseItem item, ItemImageInfo image, Int32 imageIndex, Boolean removeOnFailure)
  at Emby.Server.Implementations.Library.LibraryManager.UpdateImagesAsync(BaseItem item, Boolean forceUpdate)
[05:53:42] [WRN] [91] Emby.Server.Implementations.Library.LibraryManager: Cannot fetch image from https://m.media-amazon.com/images/M/MV5B..._UY632.jpg
System.InvalidOperationException: Unable to convert any images to local


but that doesnt explain why the images show elsewhere so i dont think it is related.
