SSH / SFTP Permission denied (publickey)

I've added the following to my sshd_config

Match Group sftponlyChrootDirectory /srv/sftpfolderForceCommand internal-sftp#AllowTcpForwarding noPermitTunnel noX11Forwarding no

I created "user" byuseradd -g sftponly usermkdir -p /home/user/.sshAnd then created authorized_keys in the users ssh folder.

Permissions on /home/user/.ssh/ is 700 and on the authorized_keys file 600.

But when I try sftp -P 12345 user@ip-address I get.

Am I missing something?Logging in with root works as expected...
