Assuming you're using MQTT5:

• on connection success event, you can look at the connack packet embedded in the event: https://github.com/awslabs/aws-crt-python/blob/edf0ef624bd84ab6d669b9b8639e2d9a43140c95/awscrt/mqtt5.py#L1250
• on disconnect event, if it was caused by a server-side disconnect, you can find it here: https://github.com/awslabs/aws-crt-python/blob/edf0ef624bd84ab6d669b9b8639e2d9a43140c95/awscrt/mqtt5.py#L1274

For MQTT311, server-side disconnects are disallowed and there is only one affirmative connack reason code (0), so there isn't really anything available.
