Powerflex Installation Ubuntu

Hi Community,

I am new to the community and Powerflex world. I am in requirement to simulate Powerflex HCI installation based on Ubuntu 20.04 with Poweflex 3.6.700.103. For this I want to create a 4-node Powerflex cluster. I am trying to push the installation via Powerflex Gateway. I am trying to set 4 MDM IPs (which will be used for SDS and SDC connection as well) and a separate Mgmt IP. I was able to upload the csv file to the gateway. But when I start the configuration phase I run into the error BAD_PRIMARY_MDM_IP and Error Could not add primary MDM 172.16.150.52 on 172.16.150.52 due to: Primary MDM IP address is incorrect executing command .. All the previous steps of verification, and installation of packages (MDM,SDC, SDS,LIA) successfully completes. I am trying to create a 3-node cluster. I have attached the screenshots for reference.
