Kafka connection : UnknownHostException

Hello Community,

We are trying to establish a connection with Kafka in Talend Studio. The connection is being established successfully, but while using the `tKafkaInput` and `tKafkaCreateTopic` components, we are facing the following error:

[WARN ] 15:56:15 org.apache.kafka.clients.NetworkClient- [AdminClient clientId=adminclient-1] Error connecting to node qdi1.5bfzmyo25mfutjqfmvvj0cmry.rx.internal.cloudapp.net:9092 (id: 0 rack: null)

Your help in this case will be appreciated.
