i use two machine with ubuntu 16.04 for Kafka, one machine open producer console and the other run kafka broker and consumer console.
But when i try to send messages i got this error in producer console:
How i solve this?
Can you please check that there are no firewalls active between the machines or that the traffic on port 9092 is enabled.
Also please check if the setting in the server.properties file does have the correct setting for listeners configuration (requires restart of kafka)
