I am running into the below error when creating compute IP. Config connector is already enabled, and it is a private cluster hosted on a shared network. Version 1.17.15-gke.800
$ kubectl apply -f webapp-compute-ip. yaml
Error from server (InternalError): error when creating "webapp-compute-ip.yaml": Internal error occurred: failed calling webhook "annotation-defaulter.cnrm.cloud.google.com": Post https://cnrm-validating-webhook.cnrm-system.svc:443/annotation-defaulter?timeout=30s: dial tcp 192.168.66.130:9443: i/o timeout$cat webapp-compute-ip.yaml

There was a change in the webhook default port, from 443 to 9443, see
Config connector version depends on GKE version, I did not have any control over it, moreover there no is public documentation available on what config connector version is available with the GKE version. There is an existing request here.
The solution was for me to add port 9443 in the firewall rule.
