WeatherChimes MQTT+Max disconnect problem 4G

[udellc]

The WeatherChimes 4G build for Sitka workshop with Max and MQTT uploads, MQTT is successful the first couple of tries, but then hangs. @WL-Richards has the current code. This is the output I get:
After the first failure, Max transmissions will still be received, but MQTT never recovers.
The Blue LEDS on the 4G board are lit up when connections are going well, but go off during the first failure and never come back on.
First sign of trouble is packet 37.
This is not good for the workshop activities because the MQTT failure state takes a very long time to work through and time out - so the WeatherChime appears to hang for over a min at a time every min or so.

Suggest to either fix issue resulting in the hang, or possibly remove the MQTT upload and use only Max if issue is unsolvable by Friday.
