Unable to delete orphaned serverless VPC IP address reservation — blocks network deletion

Google Cloud Compute Infrastructure

Description:

I’m trying to delete a subnetwork and its parent VPC network in europe-west3, but deletion is blocked by an internal IP address reservation that was previously used by a Cloud Run service.

The Cloud Run service has already been deleted. There is no VPC Access Connector remaining in the region. The address cannot be deleted manually.

Error message:

Failed to release serverless-ipv4-<RESERVATION_ID>: The address resource
'projects/<PROJECT_ID>/locations/europe-west3/addresses/serverless-ipv4-<RESERVATION_ID>'
is already being used by
'//serverless.googleapis.com/projects/<PROJECT_ID>/locations/europe-west3/addressReservations/serverless-ipv4-<RESERVATION_ID>'

Details:

  • Region: europe-west3

  • Resource type: Serverless VPC address reservation

Steps already taken:

  • Deleted the original Cloud Run service

  • Verified no VPC Access Connectors exist in the region (gcloud compute networks vpc-access connectors list)

  • Verified no Cloud Run revisions remain (gcloud run revisions list)

  • Attempted manual deletion via gcloud compute addresses delete — same error

This solved by itself with enough patience. The serverless IP got removed over night. Probably some kind of badge job running.
