Not able to connect using VNC viewer or remote desktop connection

I am able to connect to jetson nano remotely using putty.
Now I want my users access machine remotely using VNC view. When i try to connect using VNC viewer it is not connecting showing some error message as can’t make connection.
How to use VNC viewer or any other software.
Do i have to provide ip address of the machine in text box saying “Enter a vnc server address or search”. Screenshot of vncviewer is attached here
Do i need to perform some setting on Jetson nano so that user can connect or something is to be done from remote side.
Kindly tell me the steps.
