The server failed to import a shared session key due to invalid signature in a referrer identity digest.

In the past %1 minutes, the server rejected %2 shared session keys presented from the network due to an invalid signature in a referrer identity digest. This suggests an incorrect certificate configuration. The subject name of the certificate in the last failure is '%3'.
Cause: This is most likely to be a configuration problem.
Resolution:
Identify the server with the certificate that is causing the failure. If it is part of an Access Edge Server Array then ensure that all servers in the 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.
