My Google Chrome cast was working fine yesterday and now none of them are working today

I had no problems with my Google Chromecast yesterday and now all three of them are down and none of them will connect. I’ve done factory reset my device is connected to my Wi-Fi. I’ve even tried connecting Wi-Fi directly to the Chromecast. It appears that several people are having the same problem today

Did you encounter an error message that says " we couldn't authenticate your chromecast after resetting it and setting it up again?

no I did not receive that error message.

Well I solve the problem with my Google Chromecast. I just unplugged them all. It’s been several days and none of them will reset.
