Zen errror in ec2

Elastic Stack Elasticsearch
1

Hi,
I am trying to set up ES on EC2. I have set up discovery mode as ec2 in the
configuration file:

discovery:
type: ec2

ES seems to be responding fine. However, when I check the console output, I
see success message from ec2 discovery and then a failure message from zen:

[TRACE][discovery.zen.ping.unicast] [Amanda Sefton] [1]
failed to connect to [#domain][inet[/XX.XXX.XXX.XXX:9300]]
org.elasticsearch.transport.ConnectTransportException:

Please let me know what I am doing wrong.

Thanks!!

There might be connection failure from one node to the other, if the other
node has not started yet. If the other node that fails to connect to is up,
check things like security groups and the like, make sure they can connect
to each other (the host and port 9300).
