Unknown host exception

[rodolfoap]

Hi, I get this, usually on my third pod,

[2021-01-26 15:45:54,011] WARN [Controller id=3, targetBrokerId=2] Error connecting to node kafka-1.kafka.default.svc.cluster.local:9092 (id: 2 rack: null) (org.apache.kafka.clients.NetworkClient)
java.net.UnknownHostException: kafka-1.kafka.default.svc.cluster.local

Although the pod service seems online. When I enter a bash shell on the pod, such DNS name resolves fine. But the logs show java.net.UnknownHostException.

Restarting the pod usually solves the issue.

Am I missing something?

Thanks in advance, good work!
