@Prakash Punj

Have you recently tried adding the following kind of property entry inside the "ambari-agent" file ? Is it added correctly? inside the [security] block?

# grep 'PROTOCOL_TLSv1_2' /etc/ambari-agent/conf/ambari-agent.ini
force_https_protocol=PROTOCOL_TLSv1_2

.

Can you please share the ambari-agent.ini file here and also verify if the content of this file is same as pther working agent machines?

Also please share the output of the following command:

# ambari-agent --version

.
