terraform init gives "Error: Failed to download module"

I have the following configuration, and it is giving me the error below. I'm confused, because this was working before:

module "project-services" {
  source  = "terraform-google-modules/project-factory/google//modules/project_services"
  version = "4.0.0"

  project_id = var.project

  activate_apis = [
    "cloudbilling.googleapis.com",
    "cloudresourcemanager.googleapis.com",
    "dataflow.googleapis.com"

  ]
}

$ terraform init
