In an LXC setup I couldn't write to a Kafka queue from the host machine. To make this clear, the host machine was 10.0.3.1 and Kafka was 10.0.3.209.
The reason was that the hostname advertised was not resolvable from 10.0.3.1. The fix was to add an entry to the /etc/hosts for the machine were Kafka is. I am pretty sure we have discussed this in the past.
