Server Application Error.
The message with Action "BackupExec.Management.Services/AnomalyDetection/QueryAnomalyDetails' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher.
Backup Exec 22.2 introduced Anamoly detection feature. When a Backup Exec 22.2 version remote administration console tries to connect to a lower Backup Exec version console, the anomaly API attempts to fetch non-existent Anomaly information from older versions of Backup Exec which causes a mismatch and Server application error is seen.
Upgrade the lower version of Backup Exec to 22.2 if accessing it using the Backup Exec 22.2 version Remote Administration Console (RAC)
WORKAROUND:
Click the OK button on the Server Application Error pop-up.
The Remote Admin Console will proceed to connect to the lower version Backup Exec media server.
