CMAK Will not attempt to authenticate using SASL (unknown error)

kafka's are in cluster between 2 servers on this server I have 3 instances kafka with different port IOS: oracle linux 4.1.12-61.1.18.el7uek.x86_64

kafka conf/server.properties added: host.name=x.x.x.x zookeeper.connect=x.x.x.x:6081,x.x.x.x:6081 other things are basic configuraton
kafka conf/zookeeper.properties changed data dir custer zookeeper server.3=x.x.x.x:6088:6089 server.4=x.x.x.x:6088:6089

also I added a file with myid (each instances has diffrent number)

kafka manager config only changed kafka-manager.zkhosts="x.x.x.x:6081"

How I'm running kafka manager ./bin/kafka-manager -Dconfig.file=conf/application.conf -Dkafka-manager.zkhosts="x.x.x.x:6081" -Dhttp.port=80

important
Other instances on port x.x.x.x:9081 in cluster are working propertly, everything is fine
When I'm running other kafka manager on the same network subnet, why they are connecting each other?

::Update:: Found the issue, it was an internal communication problem with Kafka to Zookeeper as it was not able to reach the node. Reassigned the nodes properly and it was up and running.

How did you re-assign the nodes?
