To enable access to the www-data user, you just have to run the sudo webinoly -login-www-data=on command. As the owner of this directory on the server established by Nginx we have configured limited access and restricted access only by SFTP, thus eliminating the possibility of accessing the command line and other operating system directories.
In this way we differentiate two types of users: Users with access to the configuration of the server and the user www-data that is usually shared by web developers.
