Hello.

If you daemonize vncserver, will it not come back even if it is disconnected?

Hello.

What is your host OS?
What version of Guacamole?
What version of TightVNC?

Here on Ubuntu 20.04.6 LTS+Guacamole 1.5.1+TightVNC 2.8.75, I've tried 
connecting and disconnecting repeatedly with no errors.

Best Regards,

Hi all

I have an annoying issue with my guacamole / tightvnc setup. I can connect to 
my system only once. If the connection dies for whatever reason (usually 
hibernation of system running the browser client), I cannot reconnect to the 
VNC connection w/o restarting vncserver.

I can connect to guac, but when I try to resume the VNC connection I see an 
error. When I check syslog on the server, I see the following:

"List of security types is ZERO, expecting an error to follow"

I have to restart vncserver to reconnect.

Is that a guac issue or rather a tightvnc one? Any ideas? Is there any more 
information needed from my side to debug?

best regards
Carolin
