summary_large_image card not showing image

My summary_large_image card works fine in the validator, but the image doesn’t show on Twitter. The domain (findingtheuniverse.com) is approved, although images are served from a third party.

Hello,
I have the same problem as Lozula. I followed instructions correctly, my summar_large_image card works fine in the validator, even showing a preview of how it will look like on Twitter. When I posted the link from my blog only the link appeared as usual with no picture. Does this have something to do with Weebly which is where my blog is located?
Below is the link to the blog post with the summary card:

Thank you!
