These steps should work no matter what you're trying to cast, whether it's a streaming video, a local file, or the whole desktop or browser tab. Remember to test to see if the solution worked for you before moving on to the next step. Unplug the Chromecast, or the TV if it's built-in to it, for a few seconds and then plug it back in.

Some TVs might appear to have Chromecast built-in, when in reality, they're only compatible with certain websites, such as YouTube or Netflix, which make themselves available to our TV via the DIAL protocol. Attempting to cast something else, such as your desktop or a browser tab, will show the 'source not supported' error. Check Google's Chromecast built-in page to see if your TV actually supports Chromecast.

You might have to permanently delete one of your extensions if it's the culprit. If you have an Android TV, press Home on the remote, go into the settings, choose Apps under TV, and find Google Cast Receiver under System apps. In there, first, try toggling the option off and then back on.

Everything will be restored to its default state, so the Wi-Fi network will need to be set up again. This is different from the restart step earlier. A reset erases customizations and puts the router back to its factory defaults, while a restart is just a simple shutdown and startup.

Change your Wi-Fi network from public to private if you're on Windows. Doing so makes your computer discoverable to other devices on your network, which could fix the error. Try a different browser such as Edge or Chrome Canary (meant for developers).

Some users have had luck using something other than Chrome. At this point, after resetting all the hardware and ensuring that everything is updated, the next easiest solution you're left with is leaving Chrome for another browser.

In fact, for some people, using Edge to connect to the Chromecast might, for whatever reason, trigger or wake up the connection from your computer to the Chromecast, thus fixing the error in Chrome. So, it's worth a shot.

Reinstall your operating system. Yes, this is a huge step, but it could be the fix if the problem isn't with your TV or Chromecast. If your operating system is to blame, a fresh installation will almost always fix the error.

This will erase everything on your computer unless your reset method includes an option to keep your personal files (such as Reset This PC in 11/10/8). Remember that this will only fix the Chromecast error if the problem lies with your computer.
