    What version of Ambari are you running?

    Can you confirm the following ports are listening on the ambari server?

    netstat -anp| grep 8441
    netstat -anp| grep 8440

    Also, that those ports are reachable from the ambari agent host? Perhaps on restart, your iptables started and is blocking ports?

    Hi Patel,

    Can you please check to make sure that IP in URL string you see in logs is reachable over IPv4? Looks like Ambari server ports are open on IPv6 network. Can you please verify? You can probably fully disable IPv6 as Hadoop does not support this yet.

    Please let us know if this is helpful.

    Thanks,
    Seth

    Hi,
    Was able to resolve the issue by upgarding openssl version from 1.0.1e to 1.0.1g
