CoreDNS DNS Server Failed

[putusugik]

I'm running on Ubuntu 22.04.4 LTS (GNU/Linux 5.15.0-105-generic x86_64)
and try to setup CoreDNS but its failed with error message

`May 01 20:24:01 dns-node18 systemd[1]: coredns.service: Main process exited, code=exited, status=1/FAILURE

May 01 20:24:01 dns-node18 systemd[1]: coredns.service: Failed with result 'exit-code'.
