[Bug]: Portgroup not accessible from this host

Holorouter Version

9.1

VCF Version

VCF 9.1

Target Type

vCenter Cluster

Describe the bug

Holodeck and VCF version are both 9.1 - drop downs of the bug mask do not allow this to be selected

PortGroup is NSX based as per documentation.

New-HoloDeckConfig -Description "VCF 9.1" -TargetHost [vcenter] -Username administrator@vsphere.local -Password [password]
New-HoloDeckInstance -CIDR 10.3.0.0/20 -vSANMode ESA -Version 9.1.0.0 -DeployVcfAutomation -InstanceID vcf91 -DepotType Online

This runs fine for a while and fails with error:

18-06-2026 12:38:24 ESXBuild[6954]: [ERROR] Site Deployment failed.
18-06-2026 12:38:24 ESXBuild[6954]: [ERROR] 6/18/2026 12:38:24 PM New-VM Portgroup not accessible from this host.
18-06-2026 12:38:24 ESXBuild[6954]: [ERROR] HoloDeck deployment failed. Complete error diagnostics saved to: /holodeck-runtime/logs/holodeck-runtime-errors-site-a_18Jun2026_12_29.log
Exception: Failed to deploy HoloDeck

The cluster selected as an install target has four nodes; all of them are prepared with NSX and can access the NSX trunc portgroup. A holodeck instance with version 9.0.1 runs fine.

Reproduction steps

1. New-HoloDeckConfig -Description "VCF 9.1" -TargetHost [vcenter] -Username administrator@vsphere.local -Password [password]
2. New-HoloDeckInstance -CIDR 10.3.0.0/20 -vSANMode ESA -Version 9.1.0.0 -DeployVcfAutomation -InstanceID vcf91 -DepotType Online

Expected behavior

Create ESXi Host VMs without error
