Authentication required with public link (folder)

Hi to everyone.

I have a fresh install of NextCloud (with all the default options) and when I create a public link for a folder and used it in a browser, this ask me for authentification (user and password). See the picture.

This doesn’t happen when I share a single file. Only with folders public link.

Any ideas why is happen this?

Thanks.
