guacd[]: Unable to connect to VNC server
Hi,
I'm facing guacamole connectivity with x11vnc.
the x11vnc server is Ubuntu 18 LTS.
the guacamole server is Ubuntu 18 LTS with "guacamole-1.2.0.war"
"guacamole-server-1.2.0" "guacamole-auth-jdbc-1.2.0.tar.gz"
I'm getting the following error.
Ubuntu Syslog:

Name resolution didn't fix the issue.

The server where guacd is running cannot resolve the name of the VNC
server. You need to fix the name resolution issue - from the server
running guacd you should be able to do "nslookup <hostname>" or "host
<hostname>" or "ping <hostname>" and the address should resolve correctly.
