I have tried increasing scrape interval to 120s. Still same error log.

[raja-gola]

using curl to get the metrics works.

$ curl -k -v  https://172.42.140.9:8443/metrics -H "Authorization: Bearer <token>" 
...
....
# HELP kube_daemonset_created Unix creation timestamp
# TYPE kube_daemonset_created gauge
...
...

[raja-gola]

Increasing the scrapeTimeout has fixed the issue.

[prasadbhagwat93]

Did really increasing scrapeTimeOut solve the issue? I am hitting no end with exact same issue.

I am finding the same error message except when I start the proxy and go to the Kubernetes Dashboard.

kubectl proxy
Starting to serve on 127.0.0.1:8001
I0720 10:30:23.365488 20664 log.go:172] http: proxy error: context canceled

I was not given this error before, and am able to authenticate using a secret token on the dashboard. Nothing shows up in the dashboard when I see this error.

[rezabojnordi]

i am install dashboard in server and run kubectl proxy
error
kubectl proxy
