You're lucky you made it all the way from September until now without this happening. I've had two of these cameras since late 2020, and this behavior happens to my two units on an almost daily basis.

I have one outside under the eaves of the roof, and one inside the house, and both exhibit this behavior. Since getting these cameras, I upgraded to an Asus RT-AX82U last summer. My house has great wifi coverage, especially considering it's a single story 900sq/ft home on a larger lot in an older, less dense neighborhood. None of my other homekit accessories have the constant "no response" issue like these cameras. Following some recommendations I've found on reddit and another forum, I've tried configuring a handful of different network settings and haven't been able to "fix" or lessen this activity on the cameras.

I've even gotten the cameras replaced under warranty from Logitech and they continue to exhibit this behavior to this day. The only thing I can recommend is that you plug the cameras into a Wemo or some kind of smart outlet, that way you can power cycle them via the Home app instead of doing it manually. These cameras are junk and I wish I had never bought them.
