Caddy “listen tcp :443: bind: permission denied”

I set up an FTP server in Ubuntu using something like this guide and mine works well:

Does anything here help?

On another note, you should not change the owner of /var/www. As long as your group ftpusers has access to to it and vsftpd is running as a user that is a member of the group you should be fine.

I would use mod_userdir if I were you to configure a public_html dir in each of your users homedir.

This module allows user-specific directories to be accessed using the http://example.com/~user/ syntax.

You can enable it for only a subset of users if you'd like:

UserDir disabled
UserDir enabled user1 user2 user3 

With this in place you will probably have more luck with the perms, as it might very well be that with your conf, you're getting an SELinux denial or something on top of your permission errors.

You typically don't want to allow other users access to the users directories, which your approach would require.
