As far as I know, you need to check the site for http... but did not find anything... Maybe you will know better. ..or is there another reason?

However, if the HTTPS page you are visiting includes HTTP content, some of the HTTP content can be read or modified by attackers even though the main page is loaded via HTTPS. When HTTPS pages have HTTP content, we call that content "mixed". The page you are visiting is only partially encrypted and although it seems secure, it is not. For more information about mixed content (active and passive), see this blog post.
