I can collect node data, but k8s can't

the configuration

- module: kubernetes
  metricsets:
    - node
    - system
    - pod
    - container
    - volume
  period: 10s
  host: ${NODE_NAME}
  hosts: ["https://${NODE_IP}:10250"]
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
  ssl:
    verification_mode: none
    certificate_authorities:
      - /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

the log

Hi!

Do you actually want to use ssl? If so you need to make sure that you are using the right certificates.
If not you can just comment out these lines:

- module: kubernetes
  metricsets:
    - node
    - system
    - pod
    - container
    - volume
  period: 10s
  host: ${NODE_NAME}
  hosts: ["https://${NODE_IP}:10250"]
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
  ssl:
    verification_mode: none
    #certificate_authorities:
    #  - /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

sorry for reply later
I tried your suggestion, but it didn't work

- module: kubernetes
  metricsets:
    - node
    - system
    - pod
    - container
    - volume
  period: 10s
  namespace: 'sxc'
  host: ${NODE_NAME}
  hosts: ["https://localhost:10250"]
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
  ssl.verification_mode: "none"

Do I need to modify the ClusterRole
