Using a fresh installation of ECK Operator 2.3.0, and installing Elasticsearch version 7.16.2, Running on **Azure Kubernetes Service** , and with **ISTIO** service mesh.

The operator eventually runs fine but restarts once in a while.

Here is an error that causes restart:

The ECK operator exits because it fails to connect to the Kubernetes API server. I assume you are proxying these connections with Istio? If so, I would start looking on the Istio side why the connections are being blocked, are the proxies healthy? or are these genuine failures of the Kubernetes control plane then I would start looking into the health of the Kubernetes API server. You posted a similar question about failed leader elections here [ECK Operator - Leader Election Lost causes Restart - #2 by pebrc](https://discuss.elastic.co/t/eck-operator-leader-election-lost-causes-restart/312677/2) that points to the same underlying problem.

Thanks for the info, Peter. I'll check Istio and K8s API Server.
