Disconnect errors (error code 203)
I'm have a Guacamole server that connects to TigerVNC servers running on
virtual machines. Every now and then (roughly every 10-20 min), I get the
following error message:
CONNECTION ERROR
> The remote desktop server encountered an error and has closed the
> connection. Please try again or contact the system administrator.
Is this error ever caused by network issues between the browser and
Guacamole? Or is this only due to issues between the VNC server and
Guacamole?

Glad you found it. I think that fix will go into the next version -
provided you have the proper version of libvnc.

I did a little more digging and found I might be having this issue
<https://issues.apache.org/jira/browse/GUACAMOLE-414>. In the vncserver
logs, I found error messages regarding TLS right whent the disconnect
occurs. I'm using SecurityTypes=VNCAuth on my vnc server, and so far have
not experienced any more disconnections.

Hard to say for sure, but likely guacd <-> vnc issues. Can you get the
logs from guacd at the time of the disconnect, preferably in debug
verbosity?
