Solution #2: Enable Mirroring Service
If you’ve ever explored the Chrome browser then you might have already know what Mirroring Service is. No no, I’m not talking about its features or settings, but I’m talking about Chrome browser Flags!
In every Chromium-based browser, you’ll get the flags where you can enable or disable any option, service, or features in the browser. Since our main concern is to fix the Source not supported while casting through chrome so will keep our focus on Google’s Chrome browser.
Enabling the Error Mirroring Service allows the Chrome browser to support the TV and other casting devices like Chromecast to cast in Google Chrome. By default, the Error Mirroring service is not enabled. You can enable it by following the below steps.
Step 1: Open up your Chrome browser.
Step 2: Navigate to Flags page by typing the URL: chrome://flags/ in address bar.
Step 3: There you’ll see plenty of flags by but we’ve to find the Error Mirroring one. To find it press Ctrl + F and search for Mirroring Service.
Step 4: Enable the Mirroring Service flag by clicking on the dropdown menu next to it and restart your Chrome browser.
Next time you open up your Chrome, the Mirroring Service flag would be enabled and this might potentially solve the problem of not supported source in Chromecast.
Solution #3: Remove these Extensions if Have
While scrolling the subreddits, I found that some users are able to fix sudden source not supported error by just removing the VPNs and Adblockers extensions they’d in their Chrome browser. Luckily this turned to be work for many of them.
So we would like to also suggest you make sure you don’t have any VPN or Adblocker extension installed in your browser if you remove them by these steps.
Step #1: Open the Chrome browser and type chrome://extensions/ then hit enter.
Step 2: If you have installed any VPN or Adblocker extension, simply uninstall by clicking the Remove button below every extension.
Step 3: Restart your Chrome browser.
So this was another way to get rid of this issue, you can now check to see if your Chromecast device is casting in your Google chrome.
Solution #4: Connect Your Devices to Same Network
Besides removing the extensions, make sure your Chromecast device and your Laptop on which you’re using the Chrome browser are connected to the same network.
Sometimes your Wireless router might create different WiFi networks despite they belong to the single physical router but it might conflict with the connections between devices.
So make sure you all device are connected to same WiFi network.
Solution #5: Restart Your Laptop/MacBook/ChromeBook, Chromcast & WiFi Router
The last way to fix all this mess is to restart every device you’re using to casting. Restarting the device have worked for some reddit users so you can also try your luck with it.
So you can restart, and also enable Cast Media Route Provide to check whether it solve this issue or not.
If restarting only not able to fix your problem, then try to unplug the devices and reset them. This makes them configured back to default the way they came from the manufacturer. Even this thing worked for some users as well.
