No Image in Backend

Hi all, I have a problem in displaying the images (they are not visible and the ? appears) for almost all the photographs when I enter the wordpress backend, while it seems that the frontends are visible (I have tried on multiple devices and it seems they are visible), I have Tried clearing cache but nothing, any suggestions?

the pages are almost all, for example both the home page and https://www.buttinoni.it/fotografo-matrimonio-milano/

Thanks to whoever will answer me
