Same problem. I have three 2nd generation Nest Cams + Floodlight combos. Installed two to backyard and driveway. They are connected to continuous power supply (no switches), strong WiFi, and no WiFi credential changes. Yet they go offline intermittently for days, weeks, and even months on end. I even lost ability to turn off floodlights in G Home app, despite being connected yet offline simultaneously so I cannot turn off even without motion detected. As a Nest Aware subscriber, I’ve been sharing these problems with Google Home/Nest Support and it’s been escalated multiple times. I think it’s a Google-hosted server or firmware update issue, yet they keep suggesting a hard factory reset (which is very difficult to reach when mounted higher than a one-story level). I’ve done this countless times and the problems reoccur. G Home/Nest Support only offers that I buy replacements because they’re out of warranty despite my history of complaints while they were under warranty. I’ve been hung up on countless times as well.
The third Floodlight + Cam is still in its original packaging because I’ve been reluctant to install given all the issues experienced above.
I also have three 2nd-gen indoor/outdoor wireless Nest Cams (no floodlight) but, surprisingly, they have all worked just fine.
Google Nest support is sloppy, careless, and lies to its customers about addressing the underlying development/engineering/QA issues and proactively following up with customers on outstanding cases. I’m fed up. I’ve spent thousands on the Google Home/Nest system and subscriptions.
