I have deployed kafka but the pods are going to "CrashLoopBackOff" with a dns error,
java.net.UnknownHostException: zookeeper.msgbus.svc: Temporary failure in name resolution
The logs of coredns pods are throwing a lot of errors as,
[ERROR] plugin/errors: 2 4686730224998678655.5699833978585684595. HINFO: read udp xx.xx.xx.xx:51070->yy.yy.yy.yy:53: read: no route to host

I have opened port 53 to allow both tcp and udp traffic and am not about the cause of this issue. Any suggestions would be appreciated and let me know if you need any more debug logscreamy-pencil-82913

06/09/2022, 5:00 AMIf your Linux distribution comes with installed Firewalld or another iptables manager it should be disabled. These may interfere with rules added by Calico and result in unexpected behavior.
