Unable to install with kfctl_k8s_istio V1.2 - tls: server chose an unconfigured cipher suite

[jmdinis]

I am trying to install kubeflow on a three-node kubernetes cluster that I have running on premise behind a proxy. I have a vanila kubernetes cluster (version 1.20.4) and following kubeflow install instructions when I apply with kfctl 1.2 it fails with following output:

kfctl exited with error: failed to apply: (kubeflow.error): Code 500 with message: kfApp Apply failed for kustomize: (kubeflow.error): Code 500 with message: Apply.Run : error when creating "/tmp/kout388380370": Internal error occurred: failed calling webhook "webhook.cert-manager.io": Post "https://kubernetes.default.svc:443/apis/webhook.cert-manager.io/v1beta1/mutations?timeout=30s": tls: server chose an unconfigured cipher suite

Please could you help understand what is causing the issue?

Thanks in advance.
