I was facing the same issue while casting through Android devices, then I gave a reset to my Chromecast 3 and connected it using Google Home from an iOS device, it worked. Please try it this way.

Hi Miles_TJ,

Thanks for reaching out to the community! I understand your three Chromecasts (3rd gen) stopped casting the same day and you received the "Can't authenticate your device" message. I see you've done a lot of research and troubleshooting already, which I really appreciate. I'm here to help. To gather some more details, I'd like to ask the following questions: 

  • Which phone operating system are you using? Is it Android or iOS?
  • Do you have the latest version of the Google Home app? Please visit our helpful article to check it: Update the Google Home app.
  • Have you ever restarted your phone device?

I'll be waiting to hear from you. Keep me in the loop!

Best regards,
Juan
