Can you execute these 2 snippets and revert

 

Edit the  /etc/ambari-agent/conf/ambari-agent.ini

 

sed -i /\[security\]/a\/force_https_protocol=PROTOCOL_TLSv1_2 /etc/ambari-agent/conf/ambari-agent.ini

 

Edit the  /etc/python/cert-verification.cfg

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

 

Restart the ambari-server and ambari-agent

# ambari-server restart    [ One the ambari server ]

# ambari-agent restart   [ One the clients with  ambari  agent ]

Please let me know the outcome
