I am receiving repeated POLLHUP and reboot on my nrf91DK board (see attached log).
1) I have loaded the modem firmware with mfw_nrf9160_1.1.1.zip. (I also tried version 1.1.0, same problem)
2) I loaded the processor with the AT image in the latest release nrf9160dk_fw_2019-11-29_d3130d77.zip with the hex file images_full/nrf9160dk_at_client_2019-11-29_d3130d77.hex and then generated new Device certificates and successfully loaded them to the board.
3) I loaded the processor with the asset tracker image in the latest release nrf9160dk_fw_2019-11-29_d3130d77.zip with the hex file images_full/nrf9160dk_asset_tracker_2019-11-29_d3130d77.hex
4) I started a serial monitor on the COM port to capture the output, and then started the board.
The board starts dfu, which then starts the secure software, which then starts the application, all as expected. Next the application attempts to connect to the LTE network, it finds the nearest Telus tower (Kanata ON, Canada) and connects. After 4 seconds the POLLHUP message is received (this is expected on the first boot) and the board reboots starting at DFU again. This loop repeats indefinitely.
Connecting to LTE network. This may take several minutes.

Between receiving the IPv4 Address and the LTE link disconnect is about 4 second pause. What am I doing incorrectly?
