Thank you [NAME] for all the tips. The issue was that the Networker client was not properly registered.
Hi guys,  We have the below environment: Windows SQL Failover Cluster, 4 nodes, 4 instances without availability groups. Networker 19.4, Linux server.  I am trying to create a client from the management console, i am configuring the Virtual Node: sqlserver-cluster.domain.local, adding the physical hosts to remote access and at the next step the client creation is failing.  nsrsqlra.raw logs are below:  86373 1621253856 0 0 0 3528 14000 0 sql03.domain.local nsrnmsqlra NSR info 25 Start retrieving savesets 00 1621253976 1 0 0 3528 14000 0 sql03.domain.local nsrnmsqlra NSR notice 42 get_federated_savesets: No savesets found. 086378 1621253976 0 0 0 3528 14000 0 sql03.domain.local nsrnmsqlra NSR info 24 End retrieving savesets. 043708 1621254066 1 0 0 20964 5360 0 sql03.domain.local nsrnmsqlra NSR notice 14 Start time: %s 1 35 24 Mon May 3 15:21:06 202143621 1621254066 1 0 0 20964 5360 0 sql03.domain.local nsrnmsqlra NSR notice 35 Computer Name: %s User Name: %s 2 12 4 sql03 13 7 BackupUser37693 1621254067 0 0 0 20964 5360 0 sql03.domain.local nsrnmsqlra NSR info 57 SQL Connection to %s is created.

Is this an issue with permissions on the SQL Cluster? Permissions have been granted to BackupUser and Networker services are running with this account.  Any assistance is much appreciated.
