I am using x11vnc in ubuntu 20.04, in one of my machine, I can not authenticate VNC client from LAN computer's VNC viewer. in same machine (localhost) it is working fine.
here is my configration file /lib/systemd/system/x11vnc.service
[Unit]
Description=x11vnc service
After=display-manager.service network.target syslog.target
[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -forever -display :0 -auth guess
ExecStop=/usr/bin/killall x11vnc
Restart=on-failure

with the same configuration in another machine, it is working fine. I double check ufw rules. I tried to set a password in this configuration file as well but nothing works for me.
