vnc server - vnc setup - no password configured for vnc error

Question

what I did

sudo apt install lightdm
sudo reboot
sudo apt install x11vnc

sudo vi /lib/systemd/system/x11vnc.service

..
[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -forever -display :0 -auth guess -passwd password
ExecStop=/usr/bin/killall x11vnc
Restart=on-failure
..

systemctl status x11vnc.service 

the x11vnc.service is active running status now. through port forwarding I open internal 5900 -> external 15900 and in putty, tunneling configuration, I added 5900 and public_ip:15900

then when I try to use in realvnc-viewer url, I typed localhost:0 and the system requires password for localhost:0

• I tried tigervnc-viewer, it doesn't feel client viewer problem.

So I filled password to 'password'. I tried so many times all failed with no password configured for vnc error.

Is there solution for this?

[Solved] I didn't open ufw for 5900
