I deployed Jenkins on Kubernetes cluster.

I trying to configure slave on demand using jenkins-kubernetes plugin on the same cluster.

Over http, timeout response is returned.

Over https, this is always the same error: WARNING o.c.j.p.k.KubernetesCloud#provision: Failed to count the # of live instances on Kubernetes okhttp3.internal.http2.ConnectionShutdownException

This is the configuration

What I have forgot ? Thanks.
