Azure App Service Plan "This region has quota of 0 instances for your subscription"

Question

I'm trying to deploy a function app (EP1), an App Service Environment (I1v2), and App Service Plans in Azure, targeting the East US region. I'm using the Azure portal, CLI, and Terraform, but I keep getting this error in my terraform console after running terraform apply. It is the same error in CLI and Wizard Portal:

This is our ASE terraform definition:

resource "azurerm_app_service_environment_v3" "res-75" {
  internal_load_balancing_mode = "Web, Publishing"
  name                         = local.ase_name
  remote_debugging_enabled     = true
  resource_group_name          = azurerm_resource_group.rg.name
  subnet_id                    = "/subscriptions/${local.spoke_subscription_id}/resourceGroups/${local.spoke_rg_name}/providers/Microsoft.Network/virtualNetworks/${local.spoke_vnet_name}/subnets/${local.spoke_subnet_name_ase}"
  allow_new_private_endpoint_connections = true
  zone_redundant               = false

  cluster_setting {
    name  = "DisableTls1.0"
    value = "1"
  }
  tags = {
    Project = tostring(local.project_name)
  }
}

We have registered almost all resource providers for the subscription, every resource is located in East US, we have requested quota increase for almost all compute stacks but we are using 0% of ALL quota except for the ones that say "0 out of 0" available or troubleshoot. We have been trying to deploy every day for the last 2 weeks, so it is not a momentary error. This is a new subscription, and we have no issues in any of our other subscriptions.

If anyone knows what quota we need to deploy two App Service Plans I1v2 or EP1, that would be great. I cannot find this info online so far. We have looked over our networking and can't find any issues.

Answer 1

Following are the quota requirements of I1v2 and EP1

Probably, you are stuck on availing the I1v2 quota in my thought

Answer 2

This is definitely a quota issue that can be resolved by deploying to another region or raising a support request to Azure for further support if you insist on deploying to said region
