Connecting to MSK Serverless From Outside VPC

After setting up VPC peering, I tried connecting to MSK serverless via the Kafka Client,but the error is coming as address is not resolvable

./kafka-topics.sh --list --bootstrap-server boot-xxxxxx.x3.kafka-serverless.ap-southeast-1.amazonaws.com:9098 --command-config client.properties

I have verified the working of VPC peering.

1. what can be wrong here ?
2. Is it possible to connect to MSK serverless offering outside VPC ? if yes, how can it be done.

Thanks.
