When I try to connect I can see only blue screen with permanent "connecting" status in the window. The output from the terminal is only: KRDC: 1687 871 KRDC: rfbInitClient failed The output from the Tiger VNC Server log: # Wrong connection with Anonymous TLS Tue Aug 22 20:15:38 2017 SocketManager: accepting incoming connection TcpSocket: ACCEPT xxx.xxx.xxx.xxx Connections: accepted: xxx.xxx.xxx.xxx::xxxx SConnection: reading protocol version SConnection: Client needs protocol version 3.8 SConnection: processing security type message SConnection: Client requests security type VeNCrypt(19) SConnection: processing security message SConnection: processing security message SConnection: processing security message SConnection: processing security message SVeNCrypt: Client requests security type TLSVnc (258) TLS: Process security message (session 0000000000000000) TLS: Anonymous session has been set TLS: Deferring completion of TLS handshake: Resource temporarily unavailable, try again.

Also when I changed VNC server config and force it to use RFB version 3.3 everything works fine and KRDC is able to connect to the server. Maybe this is libvncserver issue ? -- You are receiving this mail because: You are watching all bug changes.
