Element not found (0x80070490)

Hellow! I have device muse 2.
I execute MuseModule.Scan() to know address of my muse device.
Run code:
var client = new MuseClient();
var ok = await client.Connect(MyMuse.Address);
if (ok)
{
await client.Subscribe(
Channel.EEG_AF7,
Channel.EEG_AF8,
Channel.EEG_TP10,
Channel.EEG_TP9,
Channel.EEG_AUX);

            client.NotifyEeg += Client_NotifyEeg;
            await client.Resume();
        }
        else
       {
            Console.WriteLine("Not connected");
        }

And got error:
System.Exception
HResult=0x80070490
Message=Element not found. (Exception from HRESULT: 0x80070490)
