I'm ready to through my google home deives in the garbage and go all Alexa. I've loved these devices, but now two of the six devices we have continue to say "hmmmm something went wrong". I've factory reset them, I've done the ten times reboot with them. I've restarted my router. I've done every troubleshooting step listed and they continue to error. If I don't get some help and get them fixed they go away and I'll never purchase another google product.
That certainly hasn’t been easy for you — let’s check what’s going on with your device.
A few questions:
Give these steps a try:
Make sure your Google Home Mini and Chromecast are within 15 feet of your Wi-Fi router.
Check router settings. (AP isolation must be disabled and UPnP must be enabled).
Reboot router again for 1-2 minutes.
Turn on Local network access for the Google Home app. Here's how: Privacy > Local Network > Google Home app
Looking forward to your response.
