Hi, working on RDP to Windows Server 2008 through SSH proxy I am
seeing this in X2goclient: "Authentication failed" together with

Query to remote X2Go Broker Agent (user: x2gobroker, hostname:
192.168.3.101, port: 22) failed

in debug output.

On the broker I can see this:

So x2gobroker tries to connect to x2gobroker-agent on the remote host.
But as it's a Windows Machine, there is no SSH server listening. Why
is it doing this? Here is my session config:
