Reddit thumbnails

[Warden20]

I'm using version 4.9.2, and the thumbnails in the Reddit feeds aren't showing up. This is the article view, but the same thing happens in the other views.
Here is the link to the feed: https://old.reddit.com/r/AccidentalRenaissance/top/.rss?sort=top&t=month
And here are the screenshots from FeedMe and Capy Reader. In Capy Reader, the thumbnails appear without any issues.

it's ok from my side.

I changed the view to modern and I see that there are like two images where the thumbnail does not exist but the image is there. As it is in the image. One thing I need to mention is that I use a freshrss instance.
The error persists when reinstalling the application with the default values.
The thumbnails work normally only when using local mode where the thumbnail is displayed normally
This image is when using a freshrss instance
