amazon s3 - Why are the preview thumbnails blank when I try to share on LinkedIn? -


i have article on website maintain, want share on linkedin, via "share update" form on site. possible thumbnail images being detected, , linkedin receiving correct urls images in question (they served amazon's s3 service).

inspecting page, see call made page https://www.linkedin.com/sharing/api/url-preview , json response includes "previewimages" field (under "data"."content") array of objects/dicts fields "url", "mediaproxyurl", "width", "height", , "size".

the "url" of preview images correct. copying , pasting address bar brings up. "mediaproxyurl" not load image. "size" field null.

using working reference url (an article on site), can see "mediaproxyurl" supposed linkedin's url thumbnail, , "size" supposed file size of original image.

so, why preview thumbnails blank? problem on linkedin's end? amazon s3 problem? i'm @ loss.

p.s. i've checked og:image , og:image:secure_url headers, they're in order.
