Hi,
I am trying to evaluate the https update process for the nRF9160 but I can't seem to get the device to finish the process. The download socket keeps failing out with errno 57:

However, if I use the AT Client App, I see that the device should have a stable connection at -105dBm or CESQ 36:
I am using NB-IoT on the Vodafone network, I have edited the sample's prj.conf to include APN and Modem configurations for this conection:
CONFIG_LTE_NETWORK_MODE_NBIOT=y CONFIG_LTE_PDP_CMD=y CONFIG_LTE_PDP_CONTEXT="0,\"IP\",\"ep.inetd.gdsp\""
I am using NCS version 1.2.0 and mfw version 1.1.1. Is there something else that I can change to make this work? Possibly increase the number of retries through API?
Michael
