NMM 9.1.1.1 Backup fails when clustered node is turned off

Hello NetWorker community,

This issue has to do with backing up a clustered environment. When all clustered nodes are "online", NetWorker backups are successful. When one of the clustered nodes is shutdown (as a test) the backup will fail immediately with the following error:

Cluster failovers are successful and no problems backing up when all nodes are online.

It there a possible configuration issue somewhere that I need to be aware of for this type of scenario (clustered node offline)?
