A topic was previously closed regarding this issue, but it seems to have come back up again on my ecosystem in the last 5 weeks or so. (Previous topic: https://www.googlenestcommunity.com/t5/Speakers-and-Displays/Nest-Hub-times-out-when-streaming-Nest-...)
Issue:
My wife and I use three Nest Hubs (One 1st gen and two 2nd gen) and a Nest Hub Max as baby monitors in the evenings and overnight (streaming from an Indoor Nest Camera 2nd gen). We may only use one of the hubs at a time to view the camera, but lately the video and audio feed keeps cutting out (black screen for a few moments, or stop casting altogether) every few seconds. This renders the feed unwatchable, and in some cases, we're waking up in the middle of the night and realizing the feed has cut out and risk not waking up to an upset child.
Like many other Google Home things, we've learned ways to "work around" the issue, and have found in the past month that casting to two hubs at once (or more) can often keep the connection stable and last indefinitely. But this week, this strategy is no longer working for us, and we find we're waking up in the middle of the night to restart devices and attempt it again - with unpredictable outcomes.
Other Notes:
- Using the Google Home app in our phones or tablet never has any outage (and we're on the same wifi network)
- Restarting devices (e.g. power cycling the camera or hub) might fix the issue temporarily, but this isn't a long-term solution and can be a cumbersome process in the middle of the night
- Wifi network in our home is extremely reliable (400+ mb/s), there are no extenders, and our house is small enough to support a strong connection throughout the home
- Haven't noticed any disparity between closer devices vs. further
tl;dr
- Casting Nest Camera feed to a single Nest Hub video feeds cut out frequently
- Casting to 2+ hubs at once kept a stable video feed and solved the problem, but doesn't anymore
- Casting using a phone or tablet works fine
- Power-cycling sometimes fixes the issue, but never for long
