      Description

      After creating SSH connection configuration to a FreeBSD system, when attempting to access it via Guacamole, it fails to connect. Looking further into the errors being logged. This is shown.

      Opening a SSH session to the same system via Putty works perfectly, so it seems like something about guacd is preventing from successful handshake.
