No Cast Devices Found?

There are a few reasons you may be seeing 'No Cast Devices Found' when trying to cast from Chrome:

  • Ensure that your Chromecast is set up and if possible, test that your device is set up successfully by casting from a phone or tablet to your TV. You should see the name of your Wi-Fi network on your home screen in the bottom left-hand corner.
  • Check that your computer is on the same network as the Chromecast.
  • Disconnect from a Virtual Private Network (VPN) or proxy server, if applicable. Chromecast cannot communicate with your laptop over these networks.
  • Firewall/antivirus software may prevent your laptop/desktop from communicating with your Chromecast. Please ensure that any firewall/antivirus software you may have installed on your computer isn't interfering with Chromecast.
  • If these options do not fix your issue, try rebooting your wireless router, your laptop/desktop, and the Chromecast device.

Running OSX on a Mac desktop or laptop?

  • Open System Preferences > Security > Firewall
  • If the firewall is enabled, go to Firewall options
  • If "Block all incoming connections" is enabled, disable this settings, save your settings, reboot Chrome and try again.
  • If "Automatically allow signed software to connect" is enabled then make sure that there is not an entry for Google Chrome in the application list.
  • If "Automatically allow signed software to connect" is not enabled then click the "+" button, navigate to Chrome in /Applications, and select it.

Running Windows 7 or Vista on your desktop or laptop?

  • Ensure that your network isn’t configured as a Public network
  • Open ‘Network & Sharing Center’ by clicking on the network icon in the Windows system tray or from Control Panel.
  • Under ‘View your active networks’ you should see your network (typically the name of your WiFi Access Point.) If you see ‘Public Network’ under your network with a park bench icon, then this is likely an issue preventing Chrome from communicating with your Chromecast device.
  • To change this setting, click on the network and click ‘Home network.’
  • Reboot Chrome (completely exit and start it up again) and try again. If that doesn’t work, reboot your computer/laptop and try again.

Please note: Software that installs a virtual NIC - VMware, Win8 Hyper-V, but also some NAS drivers - may cause discovery issues between a laptop/desktop and the Chromecast.
