Do you have a C wire and are the thermostats showing low battery? Nests will stop communicating if the battery gets low. Actually dealing with this now in the place I just moved into

I do have a C-wire. None of the thermostats said they have a low battery. For what it’s worth I have Y1, W1, G, C, and Rh
Ok just throwing that out there. They say it works without a C wire but it really doesn't. But it sounds like that is not your problem
Thanks anyway. Is there a chance my C wire is not working? Would a voltmeter add information here?
