https://api.ta-ose-mfg-01b.tatw.micron.com:6443/apis/metrics.k8s.io/v1beta1/namespaces/it-mfg-mms/podsIn this api request they are getting this below error:

Have checked the issue from the monitoring side because the request was from the prometheus-adaptar. But after trying the same  with different API services.

It gave the same result.
