OEM 13c secure agent is failing with javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

Today, i was doing the installation of OEM 13c Release 2 and as part of that installing the agent in the new host was error'ed óut with the below

Manually running the secure agent was also failing.

[oracle@rac2 agent]$ cd /u01/oem/oracle/agent/agent_inst/bin

[oracle@rac2 bin]$ ./emctl secure agent

Agent is already stopped...   Done.

Securing agent...   Started.

Enter Agent Registration Password :

Securing agent...   Failed.

Thus i checked the secure.log and found the message as "

2018-09-05 08:45:19,938 [main] ERROR agent.SecureAgentCmd main.353 - Failed to secure the Agent:

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

[05-09-2018 08:45:19] USERINFO ::Securing agent...   Failed.""

Solution:-The time in the client machine as not correct. Changed it using the root user

[root@rac2 agent]# date -s "22:04:00 OCT 27, 2018"

Sat Oct 27 22:04:00 EDT 2018

[root@rac2 agent]# date

Sat Oct 27 22:04:06 EDT 2018

Thereafter Secure agent command got a successful run.

[oracle@rac2 bin]$ ./emctl secure agent
