SSL VERIFY FAILED and Cannot read smaps for Kubernetes

Troubleshooting

CMK version:
Helm => checkmk-chart/checkmk 1.5.0

OS version:
Debian 12 / Kubernetes v1.27.6

Error message:

Hello,

I try to monitor our Kubernetes Cluster on premise but it fail,

I see mostly two issues,

The first one, for the cluster-collector pod,

It’s not able to talk to Kubernetes API (https://10.32.0.1) because of certificate verify failed.

My CA is self-signed and cluster-collector can’t ignore it or validate it :

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='10.32.0.1', port=443): Max retries exceeded with url: /apis/authentication.k8s.io/v1/tokenreviews (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

And I got a second issue, maybe due on the first one (I doubt), in the collector-container-metrics pods :

W1106 23:54:18.627991       1 handler.go:426] Cannot read smaps files for any PID from CONTAINER

Any idea how to resolv this issue
