The VNA Node passwords become invalid after a VNA node VM re-deployment via the NSX Manager
VMware Cloud Foundation 9.1
VNA node redeployment does not preserve the original VNA node passwords for the newly re-deployed VNA node VMs.
Apply KB, VCF NSX-T Edge Cluster Deployment Removal Tool with "--db-removal-only" option to remove the VNA cluster from SDDC-M inventory.
Wait for the next Auto-Sync to re-import it including reseting the VNA Node passwords.
