Issue

A review of the event server diagnostic window shows it is full of "Unencrypted event packet received" messages.
Product Line
EcoStruxure Security Expert
Environment
- Security Expert Client
- Security Expert controller (SP-C, SP-AC1, SP-ACX)
Cause
The previous failed controller had been setup for encrypted communications with the Security Expert server. Since the newly installed replacement controller did not have the encryption keys to be able to decode the packets from the server it was not able to be brought online.
Resolution
- On the controllers Configuration tab press the Disable controller encryption, then Yes to confirm.
- Wait for communications to be established with the controller, review the controller health status and update any modules that require it.
- To re-initialize encrypted communications with the controller press the Initialize controller encryption button to establish a new encryption key with the new controller.
