After upgrading to Symantec Protection for Sharepoint Services (SPSS) 6.0.9 or later, when attempting to send scan requests from SPSS to Symantec Protection Engine (SPE) the scan requests fail.
Error: 400 Bad Request. Reason: Token validation failed : Failed to read product name from License. Please contact your administrator to verify this message.
Symantec Protection Engine for SharePoint (SPSS) 6.0.9 has been updated with an new validation "Handshake" feature. The Symantec Protection Engine (SPE) bundled with this new version requires a valid encryption token from SPSS for scan requests to be accepted. If the token value provided doesn't match or is missing; the scan will fail.
- Install and register the version of Symantec Protection Engine for Cloud bundled with the Symantec Protection Engine for SharePoint 6.0.9 download package.
- Verify the computer time between the SPSS server and remore SPE servers are as close to identical as possible. A large time mismatch will cause the certificate validation to fail.
- Check for any network timeouts or packet shaping that would modify the ICAP request sent from SPSS to SPE.
