If you are using your Chrome browser on your computer and find that you cannot cast to your Chromecast, then you will want to make sure the “Mirroring Service” is turned on.

This has been popularly recommended by users as one of the most effective ways to fix “Chromecast Source Not Supported”. It is a bit strange to find that this setting is not enabled by default. However, after speaking with the Google support team, I think that recent Google updates that have been installed may have disabled the settings incorrectly.

Here’s how to enable Google Chrome Mirroring on your computer (Windows, Mac, or Linux):

Open the Google Chrome search browser.
Type chrome: // flags in the browser and hit Enter
Then press both CTRL + F keys on the keyboard to display the search tool. Alternatively, you can just use the top search bar (available in the latest versions of Chrome).
Type Mirroring, which we want to find and hit Enter.
You should now be able to locate the “Mirror Service” option as it will be highlighted (as shown below).

That’s! Now you can retry casting what you want to watch again to see if it is being cast to your Chromecast without displaying the “Chromecast source not supported” error message.

Restart your Chromecast router, computer, and Wi-Fi.


Aside from enabling Mirroring Service in Chrome, it’s also worth trying to restart your Chromecast, computer, and even Wi-Fi router.

Users also have suggested that after restarting Chromecast, issues stopped appearing and they were able to successfully disconnect from their computer wherever the Chromecast was connected.

For additional measurement reasons, we recommend that you restart your computer and your Wi-Fi router just to know that the problem is not with any of these sources.

This is what you do:

First, turn off the TV that the Chromecast is connected to.
Then, disconnect the Chromecast from the TV. You’ll also want to unplug the power cord from your Chromecast. Leave it unplugged for at least 1 minute.
That’s great! We will return to the Chromecast soon. Let’s turn off the Wi-Fi router now. Now if you are using an internet modem and a Wi-Fi router, you will need to turn both off. To turn off. There will be a power button on the router box, which need to press (steps may vary depending on the type of modem / router you are using).
After a minute or two, restart the modem / router and allow it to turn on again.
Now switch to your computer (Windows, Mac, or Linux, no matter what you use) and restart it.
When the computer restarts the backup, reconnect to Wi-Fi.
Now turn on the TV and reconnect the Chromecast to the TV. Don’t forget to reconnect your Chromecast’s power cord!
Finally, give your Chromecast some time to reconfigure everything and then try playing on Chrome.

Assuming you’ve done both Method 1 and Method 2 now, you should be able to throw what you want to watch on your Chromecast without any problem. However, if you keep getting the “Unsupported Font” error on your Chromecast, keep reading.

Disable all VPN and ad blocks.


Users also reported that disabling the ad blockers they have installed for their search browser to fix the problem. The reason is that ad blockers work by blocking pop-ups and preventing Javascript scripts from running. In our case, it may be what is preventing the browser from locating the font and causing the “Unsupported Font” error message.

To disable these browser extensions in Google Chrome, follow these steps:
Open your Google Chrome browser and click on the three-dot icon (next to your Google profile photo).
In the drop-down menu, select More tools and then click Extensions.
Now on the Extensions page, locate the ad blocker you are using and toggle the blue switch under the extension to turn it off (gray means it is off).

Restart your browser and try casting it back to your Chromecast.
It is also crucial to disable any proxy services, such as VPN, running in the background on your computer or mobile device. VPN services can mask your IP address to make it appear that you are in the country of your choice as the VPN server. This makes the browser confused and then throws the error.

To turn off your VPN service, open the VPN service you are using (ExpressVPN, NordVPN, Surfshark, etc.) and then press the Disconnect button.

Note

You’ll want to check if the VPN is actually disabled by going to Task Manager (Windows) or Activity Monitor (Mac) to see if the VPN is still running in the background. Make sure to stop the application so that it runs completely.

You can also choose to temporarily uninstall the VPN app to see if it solves the problem.

Install the latest Chrome updates.


Keeping up with the latest Google Chrome updates is something we should do, but honestly, most of us ignore it completely and hope that it will fix itself.

The truth is that sometimes the search engine’s automatic update feature doesn’t work, and when you go to your browser settings, you find that there are pending updates waiting to be installed.

Therefore, it is always a good idea to check in with the search browser to see if there are any updates.

If you don’t know how to manually check for updates for your Google Chrome browser, here’s how:

Open your Google Chrome browser and then click on the three-dot icon (next to your Google profile photo).
From drop-down menu , click on Help and click on About Google Chrome.
You will be redirected to the About Chrome page, where it will automatically start searching for new updates available for installation. If there are new updates available, you will want to download them.
