Link previews seem to be broken since upgrade. As you can see this isn’t from all instances so is this a federation issue or an upgrade issue?

For what it’s worth I get the same experience in Voyager app on Android as well as web-ui.

Anyone else experiencing the same?

    I have identified two reasons for broken thumbnails right now:

    1. For some, the source website is simply not allowing our server to download the image (mostly due to server issues on the remote side)
    2. For others, it seems that some types of URLs are breaking thumbnail generation. I think I found the bug here and will try to submit a fix soon.

    It’s possible what you are seeing is more visible than before due to issue #2433 which is:

    When images are broken, a blank space is all that is shown. A fallback image for broken images would make this more apparent.

    With the 0.19.4 update I notice it a lot more now and see a lot from apnews.com causing this, on my Subscribed view with [email protected] and [email protected] (and others) this morning I count:

    Sites that are fine: www.cnbc.com, www.nbcnews.com, www.bbc.com, www.cbsnews.com, newrepublic.com and a bunch of fediverse instances and other “not mainstream” sites from around the internet. it would appear that whatever has changed in code is interacting badly with certain mainstream news sites and the ability to get a thumbnail - I browsed the lemmy-ui commits and a metric ton of 3rd party dependencies were updated, gave up looking for the cause.

      This would most likely be the cause as the majority are from instances that you refer posting links from the sites you mention.
