CMMVC6219E The key server SSL certificates cannot be restored automatically from the backup. Manually set up key server encryption and then run the -prepare command again.

Explanation

If key server configuration exists in the backup that is being restored during Tier 4 (T4) recovery, any key server SSL certificates are regenerated and written to new files that are used by the restoration process. This error occurs when the restoration process fails to regenerate the key server certificates because they are too large. This error typically occurs when multiple certificates are supplied, for example when a certificate chain is used.
