Perhaps iptables or your kernel needs to be upgraded.

Can you describe a bit more your environment? (kubernetes version, cluster environment (GKE, AKS, kops, ...), how you installed linkerd (CLI, helm, cni, ...))

I am having the same issue, Kubeadm version 1.23.1, bare metal, installed with CLI, received warnings @ install:
warning: spec.template.spec.nodeSelector[beta.kuberernetes.io/os]: deprecated since v1.14, use kubernetes.io/os, same with cronjob.
I'm on ALmaLinux 4.18.0-348.7.1.el8_5.x86_64 gcc version 8.5.0 20210514 (RedHat 8.5.0-4)

calico for CNI, i'm thinking this might be related to nf_tables?
