This is my first time setting up a Chromecast unit.
Although I selected 1st generation Chromecast as device type for this post, it could be a 2nd gen unit. It is not an Ultra.
I have cycled power on the Chromecast. The unit has a solid white light.
The error is Can't Connect to Wi-Fi.
Subtitle is "make sure your network name and password are correct".
I have not been promoted for network name (SSID) or password. Where are these configured for the Chromecast?
Google Home discovered the Chromecast but said "the device has a few extra steps before you can start setup. Goto the Help Center to learn more."
At that point, searching & reading I did not find anything matching this circumstance.
Thanks for reaching out to the Chromecast Community! Let's sort this out.
Quick questions: how far is your Chromecast from the Wi-Fi router and mobile device? What is the make and model of the mobile phone you're using for set up?
