The vault NetWorker Server's NSRDR log file has the following error message corresponding to the failure. 
/nsr/logs/nsrdr.log

204591:nsrmmdbasm: Cannot run media database recovery: Action 'Media Database Recovery' refused because the server is
 currently in the 'active' state.  To run this action the server must be in the 'disaster recovery' state.

Cause

The vault NetWorker Server is in the default "active" state before starting the application recovery using Cyber Recovery Manager.

Resolution

For deployments running NetWorker 19.8 or later, ensure that the vault NetWorker Server's "Server state" in "Server Properties" is set to the "disaster recovery" state before starting the application recovery in Cyber Recovery Manager. This is detailed in the Cyber Recovery Product Guide in the Prerequisites of the "Initiating a NetWorker recovery in the Cyber Recovery UI" section.
