We have recently begun backup to a CloudBoost device at AWS. I was attempting a test restore today and was met with the following error:

42795:nsrndmp_recover: Performing recover from Non-NDMP type of device
11/18/21 17:05:55.474714 NDMP Service Debug: The process id for NDMP service is 0x114b8288
42799:nsrndmp_recover: Failed to query the address type of the NDMP data connection.
42871:nsrndmp_recover: Error during File NDMP Extraction.
6161:nsrdsa_recover: unknown host name: my-server-01
42840:nsrndmp_recover: NDMP recover failed.
42880:nsrndmp_recover: Error during NDMP recover
16279:recover: NDMP retrieval: child failed with status of 1
67847:recover: Failed to recover files: NDMP retrieval: child failed with status of 1

The "unknown host" is the Unity NAS device that I am backing up to the CloudBoost device.

Restores from our Data Domain are successful.

Backups run without issue, so I'm not sure why this isn't working. Any thoughts?
