Can you some please tell me why it doesn’t like my URL for the host?

Error: Error creating CDN Endpoint "brcgs-ngd-mig" (Profile "cdn-ngd-mig" / Resource Group "rg-ngd-mig-web-01"): cdn.EndpointsClient#Create: Failure sending request: StatusCode=400 -- Original Error: Code="BadRequest" Message="HostName \"https://ngdmigweb.z33.web.core.windows.net/\" is invalid.

Error: Error creating CDN Endpoint "brcgs-ngd-mig-reacttest" (Profile "react-test-mig" / Resource Group "rg-ngd-mig-web-01"): cdn.EndpointsClient#Create: Failure sending request: StatusCode=400 -- Original Error: Code="BadRequest" Message="HostName \"https://ngdmigweb.z33.web.core.windows.net/\" is invalid.

This is my code:

resource "azurerm_cdn_endpoint" "brcgs-ngd-dev" {
  name                = "brcgs-ngd-${var.environment}"
  profile_name        = azurerm_cdn_profile.ngddev.name
  location            = var.location
 resource_group_name = var.resource_group_name
  origin {
    name      = "ngd${var.environment}webreact-z33-web-core-windows-net"
    host_name = "https://ngdmigweb.z33.web.core.windows.net/"
  }

}
resource "azurerm_cdn_endpoint" "react" {

  name                = "brcgs-ngd-${var.environment}-reacttest"
 profile_name        = azurerm_cdn_profile.reacttest.name
 location            = var.location
 resource_group_name = var.resource_group_name

  origin {
    name      = "ngd${var.environment}webreact-z33-web-core-windows-net"
    host_name = "https://ngdmigweb.z33.web.core.windows.net/"
}

If anyone can suggest what the issue is that would be great
