Black screen on the local side with 4G on Android

I use Xamarin.Agora.Full.Forms 2.9.4 version but when i try to join without Wi-FI, my view is black and if someone joins to my channel doesn't see or hear anything.

When i enable the Wi-Fi is working perfect.

        public void Init()
        {
            _isEnded = false;
            if (_agoraService == null)
            {
                _agoraService = AgoraService.Current;
                _agoraService.JoinChannelSuccess += _agoraService_JoinChannelSuccess;
                _agoraService.OnDisconnected += OnDisconnected;
                _agoraService.OnNewStream += OnNewStream;
                _agoraService.StartSession(Room, Consts.AgoraAPI, Consts.Token, webSdkInteroperability: true);
                _agoraService.ToggleCamera();
            }
        }
