Could not connect to flink on Amazon EC2

Hi,

I am trying to setup cluster with 2 EC2 instances. Able to bring up the
cluser with 1 master and 2 slaves. But I am not able to connect to master
to submit my job.
Here is how my attempt,

ExecutionEnvironment.createRemoteEnvironment("18.225.26.184", 6123, new
Configuration());
Tried with public ip and elastic ip of EC2 master instance, allowed all TCP
connections in security settings.

Please suggest.
Attaching the log.

Thank you,
Madan.

Did you configure the IAM access roles correctly? Are those two machines are allowed to communicate?
