Hi David Orlow,
 
Thank you for reaching out. I am sorry to hear that both of your Google Nest Hubs are not working. That sounds very frustrating, and I understand your concern. I would be more than happy to find a solution to get your devices connected and working again. 
  • Which Google display device is this post in regard to? (model name, generation number)
  • For now, could you please perform a Factory Data Reset on both of your devices?
    • A factory reset will reset your Google Nest or Home speaker or display to its default factory settings.
      Note: This action will clear your data from the device and can't be undone.
  • Are there any improvements after a Factory Data Reset or is the device still not working?
I appreciate your patience and look forward to your update, thanks!
