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
