I have been trying to add to doorbells (battery), a nest cam (Indoor, wired) and a MaxDisplay Nest Camera for a few months now.  I have been able to add displays (without cameras) easily and without issue.  However, it seems anything with a camera function fails in the set-up process.  Specifically, I receive the above noted error message.  i have installed a new WIFI platform, factory reset the devices, deleted and readded the Home app, reset/restarted my router and have done everything I can find mentioned and available to no avail. This morning I spent at least an hour on a chat with Support who couldn't suggest a fix before i had to drop.  I have noticed a screen pops up VERY shortly about "connecting to a connective device" .  

Any thoughts?

I'm just another Google Nest customer who reads this forum. From past posts here, I have the impression that something in Google Nest's software occasionally corrupts a customer's Google Nest "home/structure", resulting in the kind of error you're getting, and Google Nest is either unwilling or unable to fix the problem and the workaround instead is for the customer to create a new Google Nest "home/structure" and uninstall and reinstall their devices there, and move any Nest Aware subscription they may have,

Did Support have you try creating a new Google Nest "home/structure" and try installing one of your cameras there? If that's successful, that would suggest that Google Nest has corrupted your existing Google Nest "home/structure".
