1. **Pods cannot access themselves via their Service IP**.
Many network add-ons do not yet enable [hairpin mode](https://kubernetes.io/docs/tasks/debug-application-cluster/debug-service/#a-pod-cannot-reach-itself-via-service-ip)

related to [CNI](https://github.com/containernetworking/cni/issues/476). Please contact the providers of the network
add-on providers to get timely information about whether they support hairpin mode.
