I'm getting the message "Cannot Communicate with Chromecast" when doing the final part of the set up after a factory reset.
It initially our Chromecast couldn't see the network. We reset the router, then factory reset the chromecast and went through the set up. It gives that message at the point you assign it to a room (ie we've gone through all the other steps ok)
We then tried a spare Chromecast and it's doing exactly the same. We've tried it with a phone and a tablet (for Google home) and we've reset the router multiple times. Our other Chromecasts are fine, it's just these two which refuse to work communicate with the phone or tablet for the final step.

Hey there Paul1966,
Welcome to the Chromecast Community Forum! It's interesting that you have multiple Chromecast devices, but two devices are having issues being set up. I'd be happy to help you figure this out, let me just ask a few questions:
Depending on the color of the LED light, we can try a few different steps. For now, I would just double-check this article to make sure everything looks good on your end.
I look forward to your response, and if you have any other questions or concerns for me, please let me know!
