TLS handshake error: read tcp in NATS server K8 pod

Question

I have deployed NATS using k8 repo https://nats-io.github.io/k8s/helm/charts/. I have enabled TLS and jetstream in the value.yaml as listed below

config:
  cluster:
    enabled: true
    replicas: 3
    port: 6222
  jetstream:
    enabled: true
    fileStore:
      pvc:
        size: 10Gi
  nats:
    tls:
      enabled: true
      merge: {
        verify: true,
        cert_file: '/mnt/nats-certificate/nats-playground-server.crt',
        key_file: '/mnt/nats-certificate/nats-playground-server.key',
        ca_file: '/mnt/nats-certificate/rootCA-playground.crt',
        timeout: 50
      }

  topologySpreadConstraints:
    kubernetes.io/hostname:
      maxSkew: 1

Issue is my Nats pod is see TLS handhshake error logs like below:-

 TLS handshake error: read tcp 10.244.2.29:4222->10.240.0.8:51404: read: connection reset by peer

10.244.2.29 is my Nats pod Ip and 10.240.0.8 is the node ip in k8. I have not connected any client to my nats server, still I see the TLS handshake error. I'm confused why there is TLS connection being made between the NATS server pod and the k8 node.If so, I'm not sure about how can I resolve the TLS handshake error.
