App Cards for video and GIFs show as black square and sometimes doesn't play



Hey guys,

I have MP4 and GIF content posted using App Cards from the URL to the page and when the card plays, we are getting a black square as the preview instead an actual preview. Here is a screenshot:

Any help would be greatly appreciated!


Would it be possible to share the URL or the meta tags? Without more information, a possible issue that comes to mind is our image fetcher not being allowed to access your twitter:image URL. This would be due to a lack of a robots.txt file on your domain allowing us to crawl for the image. For more info, check out this section of the Getting Started Guide.
