Issue:

I installed a new agent and I am unable to autoping it. I have already copied the cryptkey.txt file from the scheduler to the agent server. In the receiver.log, I am getting the following error:

<Regular:2>.CybReceiverChannel.receive[:233] - cybermation.library.communications.CybConversationException: Unexpected encryption type. AES received. None expected.

Environment:
CA Workload Automation AE Agent r11.3+ (All OS Platforms)
Cause:

The scheduler is using the AES encryption type (also known as the DEFAULT type) but the agent has been configured not to use any encryption. 

Resolution:

1. In the agentparm.txt, uncomment the following lines and make sure they are set accordingly:

     security.filename=/opt/CA/WorkloadAutomationAE/SystemAgent/WA_AGENT/security.txt

     security.level=off

     security.cryptkey=cryptkey.txt

2. Save the file

3. Restart the agent services
