The Access Edge Server failed to import a shared session key due to invalid signature.

In the past %1 minutes, the server rejected %2 shared session keys presented from the network due to an invalid signature. This suggests an incorrect certificate configuration. A large number of failures could indicate spoofed session key data sent by an attacker.
Cause: This is most likely to be a configuration problem in a server array.
Resolution:
Ensure that all servers in an Access Edge Server Array have the same certificate configured for the external IP address on the Edge Interfaces tab. Inspect the serial number of each certificate. If the problem persists, use the Administrator Log to help identify the source of these messages.
