Sku property is set at creation time and cannot be changed from Standard to Standard

Question

I have a public IP with Standard SKU setting, I'm deploying a traefik ingress server and whenever I do I get the error as follows:

  Warning  CreateOrUpdatePublicIPAddress  7s (x2 over 13s)  azure-cloud-provider  Retriable: false, RetryAfter: 0s, HTTPStatusCode: 400, RawError: Retriable: false, RetryAfter: 0s, HTTPStatusCode: 400, RawError: {
  "error": {
    "code": "SkuCannotBeChangedOnUpdate",
    "message": "Sku property is set at creation time and cannot be changed from Standard to Standard on resource update for resource /subscriptions/<subscription ID>/resourceGroups/<Resource Group>/providers/Microsoft.Network/publicIPAddresses/<Azure PublicIP Name>.",
    "details": []
  }
}
  Warning  SyncLoadBalancerFailed  7s (x2 over 13s)  service-controller  Error syncing load balancer: failed to ensure load balancer: Retriable: false, RetryAfter: 0s, HTTPStatusCode: 400, RawError: Retriable: false, RetryAfter: 0s, HTTPStatusCode: 400, RawError: {
  "error": {
    "code": "SkuCannotBeChangedOnUpdate",
    "message": "Sku property is set at creation time and cannot be changed from Standard to Standard on resource update for resource /subscriptions/<subscription ID>/resourceGroups/<Resource Group>/providers/Microsoft.Network/publicIPAddresses/<Azure PublicIP Name>.",,
    "details": []
  }
}

Which to me seems strange as I'm not attempting to change anything about the subscription, I just want to apply the public IP to the ingress service.

I'm attempting to deploy using Helm with a modified values file based on the original traefik helm file.

Hello @SG ,
Can you kindly check the Tier of PublicIP which was created ?
Is it Global Or Regional ? Make sure it's Tier is "Regional".

Basically Global Tier public IPs are not compatible with the AKS cluster and the load balancing being used.
