Traffic from the on-premises network is not permitted by VM and Management security groups:
Ensure that the security groups assigned to the VMs and management interfaces in AWS allow inbound traffic from the on-premises network. Without appropriate security group rules, the traffic will be blocked.
The AWS VPC traffic is blocked by a firewall in the on-premises network:
Check if the firewall on the on-premises network is configured to allow traffic from the AWS VPC. Firewalls may have restrictive rules that block incoming traffic, preventing communication.
Reference:
Refer to AWS documentation on security groups and firewalls and Nutanix documentation on configuring networking for NC2 clusters.
