Setting up SonarQube on AWS using EC2

Issue was that SonarQube default port is 9000. and by default this port is not open in the security group if you dont apply the default security group in which all the ports are open(which is Not recommended).

As suggested in comment @Issac, opened the 9000 port to allow incoming request to SonarQube, in AWS security group setting of instance. Which solved the issue.
