[X2Go-User] X2goClient with SSH key

Hello, I follow this tutoriel https://wiki.x2go.org/doku.php/wiki:advanced:authentication:passwordless-ssh but it does not work. I'm on Ubunut 16.04.3 LTS with kernel 4.4.0-97-generic. When I make a ssh user@my.server.com it's ok, I reach my server and connect immediatly. But when I use X2GoClient then I have a message : "Connection refused". I put the path of my private key on the field path for the sessions. I don't understand. Where did I miss a step? Best regards.
