I'm getting this error when running pulumi up using the python quickstart tutorial. Any ideas as to the cause?

aws:s3:Bucket (my-bucket):
    error: 1 error occurred:
    	* error configuring Terraform AWS Provider: error validating provider credentials: error calling sts:GetCallerIdentity: operation error STS: GetCallerIdentity, exceeded maximum number of attempts, 9, https response error StatusCode: 0, RequestID: , request send failed, Post "<https://sts.af-south-1.amazonaws.com/>" dial tcp: lookup <http://sts.af-south-1.amazonaws.com|sts.af-south-1.amazonaws.com> on 192.168.0.1:53: no such host

This looks like provider may have difficulty reaching your specified region. Can you verify that

aws sts get-caller-identity

works for your defined region?

Thanks for the suggestion, Josh. I ran this on the CLI:

aws sts get-caller-identity --region af-south-1

and it successfully returned with my account details, so not sure how Pulumi is calling this.
