How to fix Chromecast Source Not Supported Error?

Nowadays, Smart TVs come with a wide range of features, including online streaming, video recording, and much more. One of the most prominent features in TVs that is appreciated a lot by the users is screencasting. Now you can cast anything from the screen of your smartphone or desktop directly onto your TV. Not all Smart TVs have this feature, though, and for those TVs, Google has launched a device called Google Chromecast. You can cast content over WiFi to your TV from your phone or your laptop with this device from Google.

The Google Chromecast comes loaded with many streaming applications, which gives your TV access to services like Amazon Prime, Netflix, etc. But this device does not work flawlessly every time. Sometimes, Chromecast may not be able to detect a source you’re trying to use. And here in this article, we will take a look at all the solutions that you can try to fix it. So without any further ado, let’s get into it.

How to fix Source Not Supported error in Chromecast?

This error shows a message on the screen that reads “Source Not Supported” whenever a user tries to mirror one device onto another. One common reason behind this could be your internet connection. If there is not enough bandwidth, you will have trouble with the Chromecast. Furthermore, if there is something wrong with the settings on your mobile device, router, or the WiFi network you’re connected to, you will face this error then too. So let’s see what are the things you can try to fix this problem.

Update the app:
