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

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
