NRF Cloud connection refused (-111) when using NB-IoT

[AdrianT]

Hi,

We have a working firmware that uses LTE-M for network connectivity to connect to NRF Cloud. But upon testing with NB-IoT configuration (CONFIG_LTE_NETWORK_MODE_NBIOT_GPS=y), we are getting error -111. See logs below.

Hi Adrian! Could you confirm which SDK version you are using? Also, could you check if the UDP sample works with this network configuration?

Best regards,

Max.

I am using v3.0.1. UDP sample works with CONFIG_LTE_NETWORK_MODE_NBIOT_GPS added to prj.conf
