I'm definitely confused, I deployed my server on EKS and GKE. And tried to use statuspage webhook (subscriber) that will be sent to my server (via native Kubernetes Load Balancer from each Cloud Provider). However, it only works in EKS, we have set the same configuration: IP Whitelist, Nginx (OSS v1.11.1), firewall, etc. But in GKE we didn't see any incoming request from statuspage webhook, instead, we only can see it on EKS clearly (Header, Data, path, etc).
Is it any consideration/concern if we use GKE to receive webhook from statuspage?
