Hi, the thread at https://devzone.nordicsemi.com/f/nordic-q-a/48859/nrf9160-dk-connecting-problems-with-nrf-cloud/211627 has been very useful for me to get past several problems getting the asset tracker example to work. I connect successfully to a NB-IoT network here in Norway now, thanks to (as explained in the linked thread) setting modem mode to NB-IoT, using legacy PCO mode and using a static IP address since DNS is not supported.
Finally, the problem I am left with is "cloud_connect failed: -111". I had high hopes that a certificate update (devzone.nordicsemi.com/.../nrf-cloud-certificate-update) would solve this, but after successfully updating my certificates the same problem still persists.
I have a nRF9160 DK v 0.8.5, with modem FW updated. I can successfully connect to the network using the at_client sample. Since the SIM included with the dev. kit only supports LTE-M1 (no coverage where I am located), I am using a SIM card from com4.no to connect to NB-IoT.
Here is my output from the terminal:
