"Address not allowed" when trying to get stats summary of the node

[VahagnMian]

Summary

Getting the "Address not allowed" response with error code 400 "BadRequest" when performing API request to kube-api server for getting node's stats
Didn't notice this issue on the v1.29 version, but when you are running an old version, f.e v1.24, and upgrading to v1.29 using snap refresh, it will not bring the required fixes

Endpoint
https://x.x.x.x:16443/api/v1/nodes/worker-node/proxy/stats/summary

What Should Happen Instead?

It should return an actual non-error response with a status code of 200 about the node's statistics

Reproduction Steps

Perform this request with 'curl' or any tool f.e postman

Can you suggest a fix?

This issue is fixed by regenerating the kubelet.crt file and adding flags to the kube-apiserver arguments file, you can run this on the machine that is running Microk8s and it should fix the problem, here is the script
