Populates the aws\_clientcredential.h file with your AWS IoT endpoint, Wi-Fi SSID, and credentials 4. Formats your certificate and private key and writes them to the aws\_clientcredential.h header file ---

The setup script has to be used to create Thing, certificate and policy for the 1st time. But if the Thing already exists in you AWS account, it will throw an error. 2. It also shows that you are getting 500 error from the server. Can you run the command `aws iot list-things` on you command line to see if it works. ---

Would it be possible for you to change the region and retry. You will need a different IAM user in that region.Also, you have to run _aws configure_ again for the new IAM user Access Key and Secret Key. ---
