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
