- Platform9 Managed OpenStack - All Versions
- Platform9 Managed Kubernetes - All Versions
Cause
Bi-directional communication is required on port 443 between the host and Platform9 Management Plane in order to orchestrate operations necessary to provision cloud resources.
Resolution
- Disable any firewalls temporarily.
- Otherwise, ensure bi-directional traffic between the host and Management Plane is allowed on port 443.
