FeedWordPress not shown images

Hello.

I’m checking the feed

https://ftr.fivefilters.net/makefulltextfeed.php?url=https%3A%2F%2Fnashe.orbita.co.il%2Frss&max=3

This link is provided by https://www.fivefilters.org/full-text-rss/

I insert it into FeedWordPress, which is installed on my site with WordPress, but there is no image, there is no feed, and in the verification window it says: “Sample Item Title: Date: 04-May-24 12:51:20 pm [unable to retrieve full-text content]”

Previously, in 2015 everything was fine

But I deleted the site due to an error and the transition to php8+

Made a new website. I installed the plugin and this problem appeared. What could be the problem?

Thank you
