Hello,
I have 2 servers, I installed proxmox in both and created a cluster contains 6
kafka nodes and 3 zookeepers
Server1: kafka1, kafka2, kafka3, zk1
Server2: kafka4, kafka5, kafka6, zk2
VM: zk3
When i shut down one server, for example server1 (kafka1, kafka2, kafka3,
zk1) and then power it up Zk01 gives me an error and can't join the cluster,
and I got this error

When I restart the zookeeper service, it joined the cluster
Also when I start the zookeeper service after the boot with 10 sec, it worked
What could be the cause
