Environment

All supported DX NetOps Performance Management releases

Cause

The DA needs to be able to get to the advertised or base listener address.

Resolution

Add kafka to /etc/hosts on the DA (no restart should be required), or modify the listener to a FQDN that the DA can access and restart the Kafka server.
