-## Services with externalTrafficPolicy=Local are not reachable
-
-On nodes where the hostname for the kubelet is overridden using the `--hostname-override` option, kube-proxy will default to treating 127.0.0.1 as the node IP, which results in rejecting connections for Services configured for `externalTrafficPolicy=Local`. This situation can be verified by checking the output of `kubectl -n kube-system logs <kube-proxy pod name>`:
-
-```sh
-W0507 22:33:10.372369       1 server.go:586] Failed to retrieve node info: nodes "ip-10-0-23-78" not found
-W0507 22:33:10.372474       1 proxier.go:463] invalid nodeIP, initializing kube-proxy with 127.0.0.1 as nodeIP
-```
-
-A workaround for this is to modify the kube-proxy DaemonSet in the following way:
-
-```sh
-kubectl -n kube-system patch --type json daemonset kube-proxy -p "$(cat <<'EOF'

 ## `coredns` pods have `CrashLoopBackOff` or `Error` state
 
 If you have nodes that are running SELinux with an older version of Docker you might experience a scenario
