i am trying to query the aws using aws-sdk-go api call "ListMetricsWithContext()".

it was working fine earlier. but occasionally i get this error . following is the error :

Error:RequestError: send request failedncaused by: Post https://monitoring.us-east-1.amazonaws.com/: x509: certificate signed by unknown authority"

what should i do.

i am using a opensuse based image on my machine.
