- Ad-blocking extensions or software
- Firewall
- Antivirus software.
5. Disable All Your Chrome Extensions:
If the error vanishes after doing this, re-activate the extensions one after the other, testing every one of them to make sure the Chromecast “source not supported” error is no longer visible. You might need to permanently delete one of your extensions if it is the culprit.
6. Access System Apps:
If you own an Android TV, press “Home,” on the remote, head into the settings, select “Apps” under “TV” and then locate “Google Cast Receiver” under “System apps.” Right there, just toggle the option OFF and toggle it ON after some time. If that does not fix the error, clear out the cache.
7. Fix Date Issue:
If Chromecast functionality is built-in to your television set, there could be a time/date-related problem that has to be fixed in order to correct the “source not supported” error. Locate the date and time option in your Television’s settings and set it to be determined automatically. Choose the “Use network time.” option.
8. Reset Your Router:
This is like resetting the Chromecast but it applies to your router. Everything gets restored to its default state, therefore the Wi-Fi network will have to be set up all over again.
9. Change Your Wi-Fi Network:
You should also modify your Wi-Fi networks if you are on Windows. Doing this will make your PC discoverable to other devices on your network, which might rectify the error.
10. Try Another Browser:
Try another browser like Edge or Chrome Canary (which works for developers.) Some users say the problem disappeared when they moved on from their Chrome browser.
There you go, if you ever need to rectify the “Source Not Supported” error on your Chromecast henceforth, you now know what to do.
