Currently I am testing the coap_client and https_client sample application with nrf9160 based custom board. But the board is continously resetting while searching for the network. But after 5 - 10 attempts connection is established with NB-IoT and sample is working. When the new firmware is flashed again the reseting problem occurs. Attached the console log
