First, Ambari requires to have FQHN for all your nodes. It is best practice to assign proper hostnames on all your nodes.
A simple word-around for getting back the heartbeat on your Ambari server is to run the following on all your clients nodes:
sudo ambari-agent restart your_ambari.server.hostname.com
It worked for me on Ambari 2.0 and Ubuntu 12. Good luck!
