Pattern PNG divider file on Error 404

Hello. There is a 404 Error on DevTools of Google Chrome browser on bet3.GR Homepage (https://www.bet3.gr/), that referres to pattern.png, despite the fact that the URL of the subsequent image is active on WordPress media library: https://www.bet3.gr/wp-content/uploads/2021/01/pattern.png. It seems that this particular file cannot be found. I assume that this is a problem of tagDiv Composer, as this Pattern PNG file was uploaded to WordPress within the installation of the Newspaper theme. I guess that it have been falsely placed as a divider between elements in homepage, but I cannot locate it and I need your assistance.
