Error - NoCredentialProviders: no valid providers in chain. Deprecated.

I'm trying to setup a new ECS Instance with standard AMI in our VPC. After starting up the instance I don't see it registering with specified ECS cluster. In our ecs-agent logs, I see the following error emitted quite frequently.

Our instance have the correct ecsInstanceRole. The VPC does not have direct access to internet. I use an HTTP proxy address which is configured in /etc/ecs/ecs.config.

Is there anything else I should do in addition to setting HTTP_PROXY property in ecs.config?

If you've only set HTTP_PROXY, it's likely that the requests to get credentials from the EC2 instance metadata service are being redirected through your proxy. Can you ensure that you've set the NO_PROXY environment variable in /etc/ecs/ecs.config as is documented here?

That did the trick. Thank you very much!
