What it means
Google explains that C106, C109, C119, C224, C324, C331, C332, C363, C364, N027 and N028 mean the Nest Cam couldn't connect to the selected wifi network, and that several things could cause it. Its procedure starts by restarting the modem and router, checking the network has internet and restarting the camera. Here the camera did find the network but didn't complete the connection.
