Hi,

to connect to my sever from a browser on any PC (where download/install of java is not possible/allowed) I am trying to provide VNC over html5 by using guacamole (Ubuntu-16.04 Mate). I can connect via ssh but when trying to connect over VNC (turbovncserver 2.1.1) syslog issues the below error message and the connection does not work:

-----------------------------------------------------------------------------------------

May  2 08:23:13 ubuntu guacd[3224]: *Unsupported VeNCrypt version. *
May  2 08:23:13 ubuntu guacd[3224]: Error instantiating client: UNKNOWN

---------------------------------------------------------------------------------------------

Is there a parameter to change the security type in turbovncserver?

Thanks, Dieter
