vnc security failure connecting to vncserver. desktop encryption setting

This seems to fix a problem connecting to Ubuntu.  Encryption is set to a level from other systems to work with vnc viewer, so can be disabled.  Might not be useful if not on a secure channel.  But tested and works.  This goes to the desktop software on the Ubuntu server machine.  


gsettings set org.gnome.Vino require-encryption false

Error message (or such)
Unable to connect to VNC Server using your chosen security setting.
