How to resolve Chromecast Source Not Supported issue
1. Check the Internet Connection
The Google Chromecast device functions on the basis of the Wi-Fi network at your home. Since a router forms a web of networks for every device that gets connected to it, it is possible for some network fluctuations to occur.
If you are unable to stream on your television and it is displaying the Chromecast source not supported error’ message, you must check your Wi-Fi. Most often than not, this is the real problem behind the Chromecast source not supported issue.
It might also happen that your Chromecast does not auto connect to the WiFi network every time it restarts hence even if your internet connection is working smoothly, Chromecast hasn’t been able to connect to it yet.
So, if you have a strong WiFi signal then try reconnecting your Chromecast to that network.
2. Chromecast & Mirroring devices connected to same Wi-Fi connection
If you are getting the ‘Chromecast source not supported’ message but there is no interruption in the internet service then it might imply that your smartphone (or another casting device) and the Chromecast device are connected to different networks.
Do make sure that both the devices are connected to the same source of Wi-Fi connection and check if the ‘source not supported Chromecast issue gets fixed. Connecting to the same WiFi network is the only way, Chromecast can connect with the source device so it kind of breaks the purpose if both the devices are connected to different networks.
3. Remove Cache Data of App(s)
It has been observed that in some cases, the ‘Chromecast source not supported’ issue happens only while using some very specific apps. Evey time an app loads, it gets data from the cached files for faster operation but sometimes the cached data gets corrupted and might stop the app from working properly.
It is thus advisable to clear the cache memory of those particular apps, before streaming via the Chromecast. In order to clear the cache memory, you need to go to Settings > Apps > Manage Apps.
Then click on the app for which you need to clear the cached files. Restart your device once again. This particular method should fix the ‘source not supported Chromecast’ problem, while streaming through that application.
4. Allow the Mirroring Service on Chrome Browser
While streaming through the Google Chromecast, the Mirroring Service option on the browser should be turned on. One primary reason why the ‘source not supported on Chromecast message appears is the disabling of the Mirroring Service on Chrome browser. Here’s how to turn on the Mirroring Service:
