Can't use private key for SSH

[Stef <st...@gmail.com>]

Hi,

I've successfully ran a guacamole docker release (ARMHF).
It works well when I log in into myserver:22 (SSH), but ONLY when using 
a simple passphrase. I can't login with my private key :-/

I've used different kind of keys RSA, elliptic, with password, without 
password, nothing works.
Using classic passphrase, I see usual logs in my SSH server... but 
nothing using a key !
Like if nothing was sent from guacd...

  * On the web interface I get a "Connection failed. Please try again".
  * GUACD logs always says :
