What it actually says
The resource exists in Azure but isn't in Terraform state. Terraform refuses to silently take ownership of it.
Azure outage? No. Terraform is protecting you from overwriting something it doesn't own.
The fix
- 01Confirm the existing resource is the one you intend to manage.
- 02Import it into state (import block on Terraform ≥ 1.5, or terraform import).
- 03Run plan and make sure it's a no-op or an expected diff.

The resource ID you need for import is right there in the error.
