Describe the bug Cluster validation fails (timeouts) on the last validation step - Validate KVA with network connectivity error - Temporary failure in name resolution. AKSHCI network and internet connectivity validation failed: http-connectivity-test-aks-hci.
To Reproduce Steps to reproduce the behavior: Configure basic AKS Hybrid via WAC Wizard in nested virtualization by following below wizard config.
Expected behavior All validations complete successfully and New Cluster step becomes available in WAC AKS Wizard
Environment (please complete the following information):
Additional context Wizard Config in lab environment (nested virtualization) Static IP address allocation method System checks Windows Admin Center is connected to Azure: Connected Roles & features to install: Hyper-V, Hyper-V-PowerShell Firewall ports to open: 45000, 45001, 55000, 65000 Host configuration Management cluster name: az-mon-poc-aks Folder to store VM images: C: Virtual network name: aks-default-network Internet-connected virtual switch: vSW-AKS VLAN ID: 0 IP address allocation method: Static (Recommended) Subnet prefix: 10.10.2.0/22 Gateway: 10.10.1.1 DNS servers: 8.8.8.8,1.1.1.1,10.10.1.10 Virtual IP pool start: 10.10.2.101 Virtual IP pool end: 10.10.2.200 Kubernetes node IP pool start: 10.10.2.10 Kubernetes node IP pool end: 10.10.2.100 MAC address allocation: Automatic Azure registration Azure subscription: Azure subscription 1 Resource group: rg-euwe-aks-hybrid

This issue is simmilar to [BUG] AKS installation stuck on "Validate KVA" #363, but here the wizard fails to create a KVA.

I'm new to K8 so probably something silly or is-well-known-but-I-don't-know is written in the explanation - please take that in mind. :)
Please let me know if you require any additional information.
Thanks!
