For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the `MINIO_BROWSER_REDIRECT_URL` environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.
