We have had the older generation of nest cam for a few years now, no issues at all. Purchased the newer battery indoor and outdoor cam and have had nothing but problems.
We have tried restarting, resetting the cam, we have tried uninstalling and reinstalling the cam. I have tried uninstalling and reinstalling the app. Absolutely nothing has worked, the cam simply will not let us see the live video. We even spoke to Google support which suggested it was a hardware problem, so we returned it and got a new one, exactly the same problem!
The camera records as we can see the clips when it detects but just simply will not show us live feed.
Never had any problems with the nest app, it's the Google home app that just simply doesn't work.
Very frustrating! We are almost on route to get rid of both cams and go with ring...
I was having the problem with my new battery cam, I say having because I solved the issue. It all start happening right off the bat after the setup process was completed. During setup, live streaming was working well, but after it was completed it didn't live stream. I did a factory reset two times and after the second reset it started to work well, initially intermittently though. I don't believe it was something to do with my hardware or even the Google's cam. It seems it could have been something wrong with the google servers, at least that was what the google specialist I was troubleshooting with for 3 hrs told me. Fortunately for me live streaming is now stable and I've haven't had any further problems since yesterday that I solved the issue.
