Not able to run Linux GUI on top of NoMachine using AWS EC2 instance

[dinesh]

I have launched 64-bit RHEL6.5 ec2 instance. I have done below steps:

# yum -y groupinstall “Desktop” “Desktop Platform” “X Window System” “Fonts”
In /etc/yum.conf added below line

group_package_types=default mandatory optional

group_package_types=default mandatory optional

#yum -y groupinstall “Legacy X Window System compatibility”

Open /etc/inittab using a text editor and change following line:

id:3:initdefault: to id:5:initdefault:

# init 6

#rpm -ivh nomachine_4.3.30_1_x86_64.rpm

#I have added security port 4000 in Security group of instance for custom tcp rule.

Then i have try to connect my EC2 instance through NoMachine. But i am getting below error
