But guacd in the foreground shows that it joined a connection. > The "User @xxxxx joined connection $yyyyy (N users now present)" message is actually informing you only about the connection between the web application and guacd, not the VNC connection between guacd and the Windows machine. It indicates that the Guacamole protocol handshake for that user of that connection has completed. The underlying connection, whether that be VNC, RDP, or some other protocol, may not yet be ready. After this message is logged, there will be additional messages specific to VNC once that connection is established and functioning.
