problems (error) when trying the python pubsub code (example for iot sdk)

Question

Hello to all,  
  
I am trying to run the pubsub.py code (on AWS Cloud9, with Python 3.6), but now get the following error:  
  
File "/usr/lib64/python3.6/concurrent/futures/_base.py", line 384, in __get_result  
    raise self._exception  
awscrt.exceptions.AwsCrtError: AwsCrtError(name='AWS_IO_DNS_INVALID_NAME', message='Host name was invalid for dns resolution.', code=1059)  
\[IKP3db-g] 22:27:04,610678 - INFO - Uncaught exception. Entering post mortem debugging  
  
Does anyone know what is the issue and how to fix this ? thanks

Answer

I found the error: was a "slash" too much in the host_name, in front;  
correct use: "xxxx-ats.iot.us-east-2.amazonaws.com"
