Why is my Chromecast not working with Discovery Plus?
Discovery+ will not cast to Chromecast if the devices are not connected to the same network, screen mirroring has not been enabled on your smart TV, or your Discovery Plus account has unexpectedly expired. You must have a working internet connection that does not experience intermittent issues.
Reason 1. Different network connections
If you are in a household that operates with two different Wifi connections, you need to make sure the device your Discovery Plus app is on, and your Chromecast is connected to the same internet.
If they are both on different networks, they will not be able to find each other.
Reason 2. Screen mirroring is not enabled
You need to enable the ‘screen mirroring’ feature on your Smart TV for the Discovery Plus app to show on your screen from the device you are using.
If this is not switched on, Discovery+ will only appear on your mobile, PC or tablet.
Reason 3. Discovery Plus account has expired
If you were making use of a trial run on Discovery Plus, or you have taken out a subscription, your account may have expired without you knowing.
You will need to renew your account if you want to be able to cast to Chromecast.
If your profile details have changed and you have not updated your details on the Discovery Plus app, this could interfere with your payment going through and the app automatically kicking you out of your account.
Reason 4. Weak internet connection
Chromecast requires at least 20Mbps to be able to stream 4K content on your TV.
Discovery Plus needs at least 4Mbps for a High Definition quality video to play without any buffering or freezing issues.
If your internet connection is experiencing intermittent issues or continuously lagging, Disney Plus won’t cast to Chromecast successfully.
Reason 5. Software update required
Your Smart TV and the device that Discovery Plus is open on need to be on their latest operating system.
If there is an overdue software update for either device, this can interfere with the performance of the devices and prevent the cast from taking place.
