This is a Bug Report
Problem: I was facing an issue, that flannel CNI was throwing errors. A lot of people were facing to the same issue and fix was:
sudo modprobe overlay
sudo modprobe br_netfilter
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
Proposed Solution: Copy paste from en doc to jp.

based on uri, i hope it should be the same heading :)
Latest version: 1.33
I see that pre-flight check were removed: https://github.com/kubernetes/kubernetes/pull/123464 And the problem might be more "CNI problem", than kubernetes problem, but atleast i want to point out of the inconsistency in different language mutations.

Might be two different problem but with the same solution, which is in JP doc but not in EN.
