last week I have upgraded to 1.26 - the latest version - kubeadm, kubelet, kubectl.
I didn’t read before that that there are some changes in kube-proxy
I have elastic + kibana. There is no connection from every pod to the outside.
is there any way to fix this and how. I read about iptables but what exactly needs to be changed/removed/installed?
Kubernetes version: v1.26.0
Cloud being used: bare-metal
Installation method: apt
Host OS: ubuntu 22.04 lts
CNI and version: 0.3.1
