I am still not very clear regarding the FQDN of the system needed while registering the host.

The screenshot is attached.

Hi @Shraddha Singh,

It looks like your ambari-agent is running but its nota ble to contact the Ambari-server to TLS issue.

Can you carefully read this article and see if it helps you ?

additionaly try disable Cert verification in python refering to :https://access.redhat.com/articles/2039753#controlling-certificate-verification-7

sed -i 's/verify=platform_default/verify=disable/'/etc/python/cert-verification.cfg

Please accept this answer if it helps you

Hi @Shraddha Singh,

I encountered same issue during the ambari-agent registration.

error:

Ambari-agent registration failed with ambari-server due to below issue
EOF occurred in violation of protocol (_ssl.c:618)
ERROR 2018-11-27 13:43:19,511 NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions

Resolution:

vi /etc/ambari-agent/conf/ambari-agent.ini
force_https_protocol=PROTOCOL_TLSv1_2

vi /etc/python/cert-verification.cfg 
[https] 
verify=disable

Hope this helps!!!. Thanks

I am not able to register the host. Error: registration with the server failed. It is a single node where ambari-server and agent is installed on the same host.
