This error always stop the "mqtt_simple" application.
I have tried modem versions 1.0.1 and 1.1.0, SDK versions v1.0.0 and v1.1.0 and added this code to system_nrf9160.c - but nothing seem to fix this bug.
I am running towards a local mqtt server that I have had in operation for years.
Typically, the code runs for a while - completing fine a few transactions, and then suddenly error 3 stops it.
The topic the application subscribes to is updated every 5 minutes.
Could it be related to the PSM mode failure with iBasis SIM in Telenor network?
