My K8s cluster is running on Azure VM. I'm facing with a TLS error when I try to get something from a cluster. However the config of k8s is correct and it has the public IP I need, also it has all the required certs, and I already checked if they are correct.
But If I execute "kubectl get pods -A" it give me an output:

SERVER_IP_AND_PORT = the same IP I use to connect to the server with ssh
here is an output of "kubectl get pods -A -v=10"
