ISSUE:

 

 

I was trying to setup a new agent for testing on windows 2012 and in the windows CA log I can see this error. Do I have to uninstall WAAE agent and reinstall, or is there a quicker fix. 

 

Here are the error messages from the receiver.log :

 

<Regular:2>.CybReceiverChannel.receive[:233] - cybermation.library.communications.CybConversationException: Unexpected encryption type. AES received. DES expected.

SOLUTION:

 

Verify whether the cryptkey.txt match on the server and the agent machine. If they do not, copy the file (in binary mode) from the server to the agent machine.
