Clouddriver.service: Failed with result 'exit-code'

Hi,

Trying to configure AWS EC2 in local Ubuntu 16.04 installation. I’ve setup debug log level in CloudDriver, setup proper IAM roles… during startup, I see requests being made to https://ec2.us-east-1.amazonaws.com using temporary security token (x-amz-security-token) but ultimately the https request times out. After few retries, clouddriver exits.

Seeing similar issue with S3 storage service. After few retries, front50 exits.

Any ideas or suggestions on resolving this issue? Running out of options.

Thanks for your support.
