Coredns is in CrashLoopBackOff state with "no nameservers found" error log

I have tried to build kubernetes using kubeadm on my bare-metal server, but it seemed that coredns failed to start after installing cni (weave-net).

Two coredns containerd are now in “CrashLoopBackOff” state, and the logs of them are:

plugin/forward: no nameservers found

And the description of “kubectl describe pod” is as follows:

I have already tried using calico instead of weave, but the result was the same.
There’s no settings in /etc/resolv.conf file.
How can I deal with this problem?

Cluster information:

Kubernetes version: 1.22.1
Cloud being used: bare-metail
Installation method: kubeadm
Host OS: RedHat Enterprise Linux 8.4 (minimal install)
CNI and version: weave-net 1.16
CRI and version: containerd 1.4.11

The coredns pods worked when I switch to Docker from containerd so I may need to configure something about containerd?
And with containerd, when I write some settings like “nameserver” in /etc/resolv.conf, the coredns pod seemed to be working.
