RealVNC server installation on Red Hat 9 Enterprise EC2

Options

Hello, dear community.
I’m struggling with RealVNC server enterprise installation on a new EC2 instance with Red Hat 9 AMI.
My main goal: Allow multiple domain users to connect to the machine using RealVNC viewer.
Actions that were taken:
1. GNOME GUI was installed following this article:
[https://linuxconfig.org/install-gnome-gui-on-rhel-7-linux-server].
(https://linuxconfig.org/install-gnome-gui-on-rhel-7-linux-server)
yum groupinstall "Server with GUI"     
Installation was successful.

  1. Set GNOME to start every time the system boots up:   
    systemctl set-default graphical.target
    The machine was rebooted.

  2. Installing VNC server (6.11) using this article:
        [https://help.realvnc.com/hc/en-us/articles/360002253818].
    (https://help.realvnc.com/hc/en-us/articles/360002253818) 
    Installation was successful.

  3. VNC server license key was added 
    sudo vnclicense -add XXXXX-XXXXX-XXXXX-XXXXX-XXXXX   
    Successfully applied.

  4. Enable domain users to connect to VNC Server using system credentials:   
    echo -e 'auth include password-auth\naccount include password-auth\nsession
    include password-auth' | sudo tee /etc/pam.d/vncserver.custom

  5. Register the common PAM configuration with VNC Server: 
    echo 'PamApplicationName=vncserver.custom' | sudo tee -a /etc/vnc/config.d/common.custom

  6. Prepare a system for VNC Server in Virtual Mode:   
    Install X11 dummy drive on Redhat-compatible systems:   
    sudo yum install xorg-x11-drv-dummy   
    Configure VNC Server to use X11 dummy driver   
    sudo vncinitconfig --enable-system-xorg

  7. Configure and start VNC Server in Virtual Mode daemon   
    sudo systemctl start vncserver-virtuald.service

  8. Tried to connect to the machine using RealVNC viewer to machineIP:5999   
     Getting time-out error message.

netstat -tunlp output shows that port 5999 is listening.

What am I missing?
I really appreciate any help you can provide.

Thanks!

Thank you.
