nRF9160 not connecting to nrfcloud, continuous resets

My nRF9160 DK is not able to connect to nRFCloud.com. I did the certificate update just in case to no avail. I have made sure to update the modem firmware to 1.01 and I used the precompiled .hex file from the latest Application Firmware. It perpetually resets with this output:

Hi!

After you receive POLLHUP, could you try a manual restart of the device. 

If that does not work, please try running through this tutorial.

Best regards,

Heidi
