ConnectionTimeout for /metrics and /metrics/cadvisor in k8s

I've added the Kubernetes Monitoring Statistics extension and have been viewing the supplied dashboard. I see that one of our clusters has a lot of failing queries to path /metrics and /metrics/cadvisor with a status_reason of ConnectionTimeout and access_type of DirectIp. How can I troubleshoot this further? I've been running some curl commands from the k8s node where the ActiveGate pod is running from, as well as from a netshoot container I've added to the ActiveGate pod and I am getting responses just fine.

The curl command I have ran is below where the cluster server endpoint I get from the k8s control plan value via command kubectl cluster-info.

curl -X GET https://<cluster sever endpoint>:6443/metrics -H "Authorization: Bearer <token>"
