You can register in the SDK for callback notifications. This will alert you to any errors:

Add callbacks to monitor the broadcast’s status updates and errors.

1. Update the interface definition for the ViewController class to include the WOWZStatusCallback protocol, which monitors status updates and errors during live stream broadcast.

```auto
Implements the WOWZStatusCallback protocol@interfaceViewController()<WOWZStatusCallback>

```
