Symptom
You configure the automatic synchronization between two SAP Landscape Management (LaMa) systems.
The configuration is described in the SAP Help Portal.
Using Direct Synchronization via HTTPS, there is an error:
"Abort LVM configuration synchronization!
Failed to export configuration of LVM '<name>'. See Log Viewer for details."
Further investigation with the Security Troubleshooting Wizard of NetWeaver Administrator (NWA) reveals that the SSL initialization fails.
Failed to export configuration of LVM 'https://<name>'.
