Errno -2: Name or service not known (AWS IoT Sitewise)

Hi,

it looks like the AWS IoT endpoint which you pass with -e command line parameter is not resolvable. The iot endpoint looks similar to abcdefgh012345-ats.iot.AWS_REGION.amazonaws.com.

You can retrieve your endpoint for example with the AWS CLI:

aws iot describe-endpoint --endpoint-type iot:Data-ATS --query 'endpointAddress' --output text

You can also validate if you can resolve your endpoint in DNS.

Cheers,
Philipp
