The precheck failed while verifying the existence of the namespaces on the TKC or upstream Kubernetes cluster.

Problem

The namespaces that the system creates during the NSX Application Platform deployment exist on the TKC or upstream Kubernetes cluster and can cause a deployment failure.

Cause

The TKC or upstream Kubernetes cluster has existing namespaces that the system created during a previous NSX Application Platform deployment.

Solution

Delete the existing namespaces from your TKC or upstream Kubernetes cluster. The system must create the namespaces during the current NSX Application Platform deployment only.
