Hi, sorry for the confusion, here is details: I have 3 broker nodes: 192.168.20.223 / 224 / 225
When all kafka services are UP: [image: image.png] I stopped the kafka service on *node 225*: [image: image.png] Then i tried the command on node223 with --bootstrap-server 192.168.20.223:9092,192.168.20.224:9092,192.168.20.225:9092: [image: image.png] *Caused by: org.apache.kafka.common.errors.TimeoutException: Call(callName=findCoordinator, deadlineMs=1705743236910, tries=47, nextAllowedTryMs=1705743237011) timed out at 1705743236911 after 47 attempt(s)Caused by: org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment. Call: findCoordinator* even after minutes, i got same error.
