Check local network permission for Cast on Apple devices

2026-11-13

Google documents local-network access for discovery on Apple platforms that enforce this permission. A Cast-enabled app can play locally while its receiver list is empty.

Confirm the exact product or platform

What to do on your device

1. Confirm that the sender and receiver can use the same local network.
2. Check Local Network access for the exact sender app on supported Apple software.
3. Reopen the app and compare discovery with another already-authorized Cast sender before changing receiver settings.

Test the viewing task

Use one authorized programme with a known audio or caption track. Check the same task after the documented change. If the result differs, report the model, OS or app version and the format or connection that the guide above applies to.

Fix discovery before changing playback settings

On iOS and iPadOS, a streaming app can reach the internet while its access to the local network is off. Apple’s permission controls are per app. On the iPhone or iPad, open Settings, Privacy & Security and Local Network and check the intended Cast-enabled app. Allow it only if you are comfortable with that app finding devices on the network.

Check that your phone and receiver are using the same home network. A guest network can isolate devices even when both have working internet. Return to the app, reopen the Cast menu and compare the list with a known working Cast-enabled app or Google Home.

Treat receiver discovery and successful playback as separate results

If another app sees the receiver and yours does not, note whether your app has local network access and whether it documents Cast for the device you use. If both apps see the receiver but only one programme fails after you select it, focus on that programme’s playback support. Check the receiver format and account entitlement once discovery works.
