Unable to connect from kubectl CLI to BTP Kyma Runtime

Dear Community,

I am facing issue while connecting BTP Kyma trial runtime cluster from my local machine CLI using Kubectl installed. I have followed SAP learning documentation and completed all the steps.
learning.sap.com/learning-journey/deliver-side-by-side-extensibility-based-on-sap-btp-kyma-runtime/setting-and-configuring-kubectl-for-kyma_b3d25bea-0ef5-498e-bd15-10ef0c23ed06

1) Installed the kubectl CLI

2) Installed krew and installed login plugins -> kubectl krew install oidc-login

3) kubeconfig downloaded from btp kyma runtime and environment variables set.

4) when try to run clusters command getting below error || kubectl cluster-info

Kindly help to resolve this error.
