Welcome to Android Central! Here's the solution on the Chromecast support page:

I've already set up my Chromecast. How can I change the WiFi network my Chromecast is connected to?
To change the Wi-Fi network connected to a Chromecast device, follow the steps below:

1. Open the Google Home app.
2. Tap the DEVICES tab to see your available Chromecast devices.
3. Scroll to find the device card for the Chromecast device you'd like to connect to a different Wi-Fi network.
4. In the top right corner of that Chromecast device card, tap the device card menu
   
   > Device settings > Network > Forget this network > Forget Wi-Fi network.
5. You'll need to set up your Chromecast device again on a new network.
