Issues with my PC's connection to the MQTT Broker in AWS IoT Core 😓

[PedroNassif]

I'm trying to create a script for my project to connect a PC with my MQTT broker in AWS IoT Core.

I'm using Windows and haven't been successful.

I've consulted the tutorials in the AWS Documentation, but I keep encountering the same traceback message:

"Traceback (most recent call last):
  File "D:\Downloads\aws-iot-device-sdk-python-v2-1.19.1\aws-iot-device-sdk-python-v2-1.19.1\samples\basic_connect.py", line 55, in <module>
    connect_future.result()
  File "C:\Users\Usuario\AppData\Local\Programs\Python\Python312\Lib\concurrent\futures\_base.py", line 456, in result
    return self.__get_result()
           ^^^^^^^^^^^^^^^^^^^
  File "C:\Users\Usuario\AppData\Local\Programs\Python\Python312\Lib\concurrent\futures\_base.py", line 401, in __get_result
    raise self._exception
awscrt.exceptions.AwsCrtError: AWS_ERROR_MQTT_UNEXPECTED_HANGUP: The connection was closed unexpectedly."

So I've tried to use the samples in the command line. I'm using PowerShell and this happens:

As you can see, it's the same error message that I've been encountering. Something is going wrong with the Future result, and I don't know how to fix it. I'm almost sure that my 'thing,' 'policy,' and 'certificates' are correct because I've already connected an ESP32 to the same broker. Can somebody please help me?
