On connection recovery, I got the following error if last_will is not specified in config. This does not affect initial connect().

Connecting to broker.
Task exception wasn't retrieved

Please could you try the demo clean.py. This does not set the last will and has been extensively tested.

Can't replicate this right now :-(. whether clean.py or my script. Close for now.
