Hi, I am trying to setup a second Chromecast 3 at home, every thing is fine until I get to the Wifi connection, then I get "Could not communicate with your Chromecast", When I press retry I get "No device found" but the App has already connected to the Chromecast so I know it's working, My other Chromecast is still working fine.
Thanks for reaching out and sorry to hear that you are having an issue setting up your Chromecast (3rd gen). Let's sort this out.
Quick questions: what's the LED light status in your Chromecast (solid or flashing white)? What's the distance between the router and the Chromecast device? Please manually connect to the Chromecast SSID. Here's how: Go to the phone’s Settings > Open WiFi and connect to the Chromecast SSID (Example: Chromecast1234, Living Room TV, Bedroom TV, etc.) > Go to the Google Home app and try to set up again.
For additional steps, please visit this support website article and let me know how it goes.
