Chromecast setup failing or Google Home app can't find it
Make sure your phone and Chromecast are on the same WiFi network before you start setup. Unplug the Chromecast for 30 seconds to restart it. Confirm the Google Home app is up to date and you're logged into the right Google account.
Chromecast setup needs your phone and the Chromecast on the same WiFi network, both devices powered on, and the Google Home app up to date. When setup fails, it's a network mismatch, Chromecast not powered on, outdated app, or WiFi connection problems. Testing network connection is the first step.
