TV missing from the Cast list: network and permissions
If video plays on the phone but the receiver is missing, device discovery may be failing before content reaches the TV. Start with the network and app permissions.
Confirm both network names
The phone may be using mobile data while the television is on home Wi-Fi. Read the network name on both devices and distinguish the guest network from the main network. Confirm that the app actually supports Cast. Being able to open the TV’s own menu does not prove it is discoverable from the phone.
Review local-network permission
Google explains that Cast discovery requires local-network permission on relevant iOS and macOS versions. A denied permission may prevent a supported app from finding the receiver. Check the app’s system permissions; the exact settings path depends on the operating-system version. Google: local-network permission for casting
Account for a shared network
A hotel or guest network may isolate connected devices. Do not change a network you do not administer; ask its operator which connection method is supported. At home, report the phone, TV and app versions together. Since the content has not yet reached the receiver, buying another streaming subscription is not the first troubleshooting step.
Your practical checklist
- Phone and TV network names
- Cast-capable app
- Local-network permission
- Home or isolated guest network
