amazon ec2 4 node cluster shows lost heart beat for all services and not able to start any services

Not enough details provided like HDP version, Ambari version

ambari-agent restart in all the nodes and see if it helps.

node 1: ambari-server & ambari-agent

node 2: ambari-agent

node 3: ambari-agent

node 4: ambari-agent

restarted all agents, still in the ambari dashboard all hosts says heartbeat failure.

I'm using elastic ip with amazon ec2

Please see my host config screen.

also i updated the file /etc/ambari-agent/conf/ambari-agent.ini to point to ambari server

[server] hostname=52.33.91.17

url_port=8440

secured_url_port=8441
