Release : 20.3
Component : UIM - DATA_ENGINE
data_engine 20.31
The data_engine as of version 20.31 does not support MultiSubnetFailover and data_engine parameter should be set to false.
MultiSubnetFailover=False
Data_engine probe 20.31 and earlier versions use OLE DB driver for MS SQL and hence does not support multisubnet failover for Always On replicas, according to AlwaysOn Multi-Subnet Failover and SSIS and OLE DB Connection Manager
