Set the clock to 8 march on Android Phone (doesnt work with Iphone).
Connect chromecast again. Then power the chromecast off and on.
(remember to update to newest version of Google Home). Worked here....
Try plugging the power the Chromecast off and on. Restart google home on
phone. That worked for me after a factory reset ( PS: Update Google home
to newest version)
Works here now. I change the phones date to 8 march and set up after
factory reset. Poeer off and on the chromecast and restart home and
change the date back. Voila!!!
