Issue
- Configuration backup uploads fail from one node with the following error:
 
::> set advanced::*> system configuration backup upload -node cluster01-01 -backup cluster01.weekly.2023-09-10.00_15_01.7z  -destination ftps://vsftpuser:xxx[]xxxx@bkp-destUploading the configurationbackup file.Uploading configuration backup file.Error: command failed: Upload operation of configuration backup file exited witherror: Failed to upload configuration backup file "/mroot/etc/backups/config/cluster01.weekly.2023-09-10.00_15_01.7z" to"ftps://vsftpuser:xxx[]xxxx@bkp-dest/cluster01.weekly.2023-09-10.00_15_01.7z". Error: Couldn't resolve host name :Could not resolve host: bkp-dest.- Other nodes in the cluster work as expected.
 - Using the backup host's IP instead of the hostname also works for all nodes.
 - The hostname is resolvable sometimes:
 
::*> vserver services name-service getxxbyyy gethostbyname -vserver cluster1 -hostname bkp-dest -node cluster01-01Host name: bkp-destCanonical name: mycompany.domainIPv4: 192.168.x.x- Adding a manual DNS entry into ONTAP stopped the errors:
 
::*> vserver services name-service dns hosts create -vserver cluster1 -address 192.168.x.x -hostname bkp-dest
