trafficlight.py throwing "AWSIoTPythonSDK.core.protocol.mqtt_core - ERROR - Offline request queue has been disabled"

Hi,

i am going through GG getting started guide, however, i am stuck at module 5, 3b. (https://docs.aws.amazon.com/greengrass/latest/developerguide/comms-disabled.html)

seemed like a common problem as someone posted the same in github without any solution https://github.com/aws/aws-iot-device-sdk-python/issues/141

as module 6 and 7 have dependencies on module 5, i want to complete it successfully. can someone help?

here's the error that i am seeing when i execute the py script. tried it on both Mac and Windows. seeing the same output.
