Hi @Sadam97,

if your account uses a customer-managed VPC, you need to manually add a firewall rule to permit traffic between Databricks-managed VMs within your VPC

You can test the connectivity to the Databricks secrets API endpoint from within the GCE job cluster to ensure there are no network issues. Use tools like curl or telnet to check if the endpoint europe-west3.gcp.databricks.com:443 is reachable
