I am running three cameras on my CK Gne2+. It all works fine. I have a noob question - why can't I see the live camera image when my WAN is down? Today Comcast was out for some time and though I could log into both SDN and Protect I could not see the camera pictures live. I disconnected from the cloud just to be sure and still the progrtess bars on live screen go all the way and then stop at the last second before reaching 100% and no live pictre shows up. My internal network is working fine. I have a USG between service porovider and LAN. My conputer and the CK Gen2+ are connected to the smae switch where two cameras are connected while the third one is at another switch.
I just need to understand why this is happening and if this is something in my network that I can fix. I imagine I should be able to see the camera images locally regardless of the internet being down.
Thank you for any thoughts.

@LLigetfa My iPad did not work so I fired up my trusty desktop hard wired to the same switch as the cameras and CK Gen2+. There has to be some technical reason somewhere or maybe there is some setting in my network that I have kluged up.
Computers work locally right now, but the iOS / Android app’s don’t support local connections yet. This is so Ubiquiti can better test out thier cloud as that is the main resource they expect users using.
The mobile apps use WebRTC to broker the connection - long story short, when the app wants to connect, the app and NVR use a STUN server on the internet as a common known service to exchange a list of possible candidate IP addresses where each can be reached at. Each host will list their available known private LAN IPs and WAN IPs, and they will then try to connect to each other using that list (starting with private IPs). If the internet isn't available, neither can reach the STUN server to exchange those candidate lists.
You can still connect to the NVR using the web interface and the local IP address if you don't have internet access.
