We have integrated the social Share Icons and define a social share image during output.
The output looks fine:

Preview in firefox with the open graph preview seems to work.
if i previewed it with twitter cards i get this:
INFO: Page fetched successfully
INFO: 16 metatags were found
INFO: twitter:card = summary_large_image tag found
INFO: Card loaded successfully
but the image is not included in the card.
same if i share it on a mobile with whatsapp. the og:title and og:description are sharing but not the picture
url is https
