note that --zookeeper is the location of the zookeeper server, not Kafka broker.

Are you running zookeeper on both 192.168.100.91 and 192.168.100.92?

Zookeeper is based on simple majority, therefore you can't run it with
2 nodes (well you can, but it will freeze if you lose one node), you
need either 1 or 3. In your case it makes sense to have two Kafka
brokers and one Zookeeper node (which you already have on
192.168.100.91).
