Hi,
I have added a nrf-9160 DK device to nrf cloud and it is always is shown as disconnected (disconnect reason MQTT_KEEP_ALINE_TIMEOUT ).
Previously i have updated the last modem and applicaction firmware. Moreover when i open the LTE Link Monitor and I enter an AT command I always get the following error:
'AT+CFUN?' timed out
The nRF SDK version I am running is v1.7.1. Before updating the modem and application firmware AT commands were enabled and Modem was green. I send you a screenshot of LTE Link Monitor
below is the output of logfile in LTE Link Monitor:

Hello,
Thanks for sharing these details. What version of the nRF9160DK are you running? I tested here and noticed that my LTE Link Monitor had the wrong COM port (will investigate internally). Could you please try to change the modem port in LTE Link Monitor:
Note that the nRF9160DK has three virtual COM ports.
Kind regards,
Øyvind
