  <li>Reference Link: <a href="https://cloud.google.com/vpc/docs/configure-serverless-vpc-access" rel="nofollow noreferrer">Serverless VPC Access</a></li>
  <li>Tried all steps in <a href="https://cloud.google.com/vpc/docs/configure-serverless-vpc-access#troubleshooting" rel="nofollow noreferrer">Troubleshooting</a> - mentioned at the bottom of the above page</li>
  <li>Tried various IP ranges like 10.8.0.0, 10.128.0.0, 10.160.0.0 - no use</li>
  <li>Created a new project and tried to create the access there, same result</li>
  <li><strong>Works</strong> if I change the region to <strong>us-central1</strong> (instead of <strong>asia-south1</strong>). See below</li>
  </ol>
  <pre><code>gcloud compute networks vpc-access connectors create cloud-sql-connector \
      --network default \
      --region us-central1 \
      --range 10.8.0.0/28
  
  Created connector [cloud-sql-connector]
  
  gcloud compute networks vpc-access connectors describe cloud-sql-connector --region us-central1
