Hi! How can i add a ssh user such that

its only access is /var/www/html?

What i did: added a user "ftpaccess" with group www-data, the home dir set to /var/www/html and created .ssh dir. Added my pub key details (jaey_id_rsa.pub) in authorized_keys. Also i added AllowUsers ftpaccess in /etc/ssh/sshd_config.

It always returns ftpaccess@server.domain: Permission denied (publickey)

Whats missing here?
