Azure Front Door CORS rules stuck in "NotStarted" deployment status - configuration changes blocked

I have an Azure Front Door Standard profile with CORS rules configured but not deployed.

Issue:

  • Status: deploymentStatus = "NotStarted"
  • Error when trying to update: "BadRequest: All Changes to Azure Frondoor Configuration are blocked currently"

Impact:

Production application is failing CORS preflight requests with 405 errors, blocking all browser API calls.

  • Rules are properly configured to handle OPTIONS requests and set CORS headers
  • Unable to modify or trigger front door rules deployment via Azure CLI or Portal
  • Front Door profile status shows: ProvisioningState=Succeeded, ResourceState=Active

How can I trigger deployment of these existing CORS rules to the Front Door edge nodes?
Why are configuration changes blocked?
