I started a new ticket since I got a solution to not connecting to the cellular network. Apparently the iBasis sim is not working so I acquired a Hologram sim. I now can connect to the cellular network but the nrfcloud will not allow connection to the nrf9160 DK board. (see log below). I reflashed the asset tracker firmware, the modem firmware and created new certificates and successfully loaded the certificates into the nrf9160 DK. I then installed the Hologram SIM. I also did a "reset device" in the NRFCloud before I generated the certificates since I did have this board working and connecting last July.
I would appreciate any suggestions.
Following are the hardware software specifics I have.
