title: AKS creation through CLI fails: Reconcile standard load balancer failed
body: <p>I have created the AKS using below CLI command on countless number of occasions. I had no problem until today.</p>
  
  <pre><code>az aks create --resource-group rg  --name ama --generate-ssh-keys --location southeastasia 
  --aad-server-app-id xxxxx-xxxxxx-xxx-xxx-xxxxxxxxx --aad-server-app-secret @xxx?=1[xxx:xxx:xxxx:xxxx  
  --aad-client-app-id xxxxx-xxx-xxx-xxx-xxx   --client-secret xxxxx-xxx-xxx-xxxx-xxxxxxxx 
  --aad-tenant-id xxxx-xxxx-xxxx-xxxx-xxxx  --service-principal xxxxx-xxxx-xxxx-xxxx-xxxxxxx
  --node-count 3
  </code></pre>
  
  <p>Today, I am getting the below error. I tried two different regions and two different subscriptions.
  but same error.</p>
