Link cards have black or no preview thumbnail

[Big71]

Describe the bug Since a few days I have a problem with the preview images of Wordpress links.

For example: I want to share a link from my Wordpress blog on Bluesky via a Browser (Firefox or Brave). I create a new post for this. There I copy/paste the link and then select the option "Create linkcard". The linkcard is then also created, but without a preview image or only with a completely black preview image.

What I have already tried:

• Sharing links from another blog (also Wordpress 6.5)

• Visited Bluesky via a different computer / different IP / VPN

• Changed the preview image in my blog article

• Tried a fresh Wordpress installation without plugins

• Tried all combinations of article image, post image, YoastSEO & Co.

• Tried sharing the links via the Android app

• Tried to share older posts from my blog

• Used the Bluesky account of a friend

• Used a different browser (Firefox, Brave, ...)

• I even created a Wordpress blog with another web host to rule out problems with my own web host (all-inkl.com)

• The TLS protocol versions that are enabled on my site are TLS 1.3 & TLS 1.2

• The preview images are displayed correctly on Facebook, Instagram and Twitter

• Checked the URL with https://www.opengraph.xyz

• Force https disabled for my domain

• ...

None of this was successful and I'm slowly at my wit's end.

Is this a bug in Bluesky? Is this possibly a Wordpress problem?

Any help is appreciated. Thanks a lot.
