Chromecast Connection Failed

[DA1000]

I got a new router and my Chromecast is refusing to connect to it. The Google Home App says "Connection failed-Couldn't connect to Chromecast. Make sure local network access is enabled for the Home app in your phone's privacy settings. Then try again."

Local network access is enabled and I tried again but got the same error. I did a factory reset on the Chromecast but got the same error again. Currently it's rapidly flashing white.

Try these steps:

1. Make sure your Chromecast is within 15 - 20 ft (4 - 6 m) of the Wi-Fi router. If you have a dual band router, try to set up your device on both the 2.4 GHz and 5 GHz bands.
   
   
2. Make sure Wi-Fi and Bluetooth are both turned ON on your phone or tablet.
   
   
3. Turn OFF mobile/cellular data.
   
   
4. Reboot your router. Most routers just require that you unplug the power source and then plug it back in to reboot.
   
   
5. Reboot Chromecast by removing the power cable, then reconnect it.
   
   
6. Make sure you're using the latest version of the Google Home app, by checking your app store for any updates.
   
   
7. Restart the Google Home app.
   

• Android: Swipe up from the bottom, hold, then let go. Swipe up on the Google Home app.
• iPhone/iPad: Swipe up from the bottom, hold, then let go. Swipe up on the Google Home app. On older devices with a home button, double-click the Home button, then swipe up on the Google Home app.
• Turn Wi-Fi off and on again on your phone or tablet.
• Reopen the Google Home app.

If none of the steps above help, factory reset your Chromecast and then retry setup. You may also want to try setup using a different phone or tablet, just to test, if you have one.

I did most of those steps before posting, but after posting it suddenly started working again.

Glad to hear! Happy to advise if it becomes an issue for you again in the future.
