Please verify if IPtables.service is configured in your environment by running the below command:
#sudo iptables -L -v (List current rules)
If yes, please flush the rules and disable the service, since it is unsupported for Data Sense instances:
#sudo iptables -P INPUT ACCEPT
#sudo iptables -P FORWARD ACCEPT
#sudo iptables -P OUTPUT ACCEPT
To make the changes persistent across reboots:
# sudo systemctl disable netfilter-persistent
Post making the above changes, please uninstall and reinstall Data Sense in the VM by following the documentation below:
https://docs.netapp.com/us-en/bluexp-classification/task-uninstall-data-sense.html#uninstall-bluexp-classification-from-a-cloud-deployment
If no IPtables are configured, we would recommend you to open a NetApp Support case to track this issue better and troubleshoot further.
