Following the upgrade of Messaging Gateway (SMG) to version 10.7.5 attempts to remediate incidents in DLP via the Flexresponse plugin return the following error:
Input error when reading response from email gateway: java.io.IOException: Server returned HTTP response code:
500 for URL: https://smg.domain.com:8443/brightmail/ws/DlpQuarantineActionsService
Release : 10.7.5
Component : DLP Flexresponse API
This issue is currently under investigation but appears to be associated with x509 extensions in the client certificate used for API authentication.
service controlcenter restart
A simplified and updated client certificate should resolve the API authentication issues. If you continue to see errors from the DLP Flexresponse API, please contact Messaging Gateway support.
