Open question about OpenGraph to any geek who feels like responding 😄

BlueSky and LinkedIn fail to fetch the featured image for posts on axbom.com (my English site) but does it with no issues for posts on axbom.se (my Swedish site).

From my perspective they are set up in exactly the same way (Ghost sites). My estimate is that this started happening more than a month ago and I have no idea why.

So, what could be the issue?
