No puedo conectarme al servidor via ssh URGENTE

["Yoandy Melero" <yoandy@ci.cf.rimed.cu>]

Amigos. hoy temprano estoy intentando conectarme al servidor via ssh como root y me
dá Acces denied

tenia puesto unas directivas para solo permitir al usuario root y al usuario yoandy:

AllowUsers yoandy root
MaxAuthTries 3

bien. comenté estas lineas de nuevo. reinicie el servicio y sigue dando access
denied. incluso reinicié el servidor completo.

aqui les pongo la configuracion.
