Make sure your Controller backup plan includes the secure credential keystore file .appd.scskeystore. In the case that the secure credential keystore file should become corrupted, restore the .appd.scskeystore file from backup.

If you run the Controller in high availability mode, both the primary Controller and the secondary Controller must use the same secure credential keystore file. If you use an HA deployment strategy, verify that it propagates the secure credential keystore file from the primary to the secondary.
