Starting backup of database appdefenderdb.
Participating nodes: v_appdefenderdb_node0001, v_appdefenderdb_node0002, v_appdefenderdb_node0003.
Error: SQL command "select instanceid from v_internal.vs_local_nodes;" failed: ROLLBACK 4236: One or more nodes did not open a data connection to this node. This may indicate a network configuration problem. Check that the private interfaces used for communication among the cluster hosts reside in the same subnet and are returned first by host address lookup
