After enabling encryption server disconnects client after OpCustom

Hi,

I tried to get encryption up and running but after doing the initial setup the server disconnects the client on OpCustom.

Client-Code:

PhotonListener listener = new PhotonListener {Main = this};
Peer = new PhotonPeer(listener, ConnectionProtocol.Udp) {ChannelCount = 10};

and

public void OnStatusChanged(StatusCode statusCode)
{
Main.Dispatcher.Invoke(() =>
{
Main.StatusTextBox.AppendText(DateTime.Now.ToString("yy-mm-dd hh.mm.ss.ffffff") +
" - OnStatusChanged called with: " + statusCode + "\n");
Main.StatusTextBox.ScrollToEnd();
if (statusCode == StatusCode.Connect)
{
Main.Disconnect_Button.IsEnabled = true;
Main.PeerConnected = true;
Main.Peer.EstablishEncryption();
}
else
{
Main.Disconnect_Button.IsEnabled = false;
Main.Connect_Button.IsEnabled = true;
Main.StatusIndicator.Fill = new SolidColorBrush(Colors.Red);
Main.PeerConnecting = false;
Main.PeerConnected = false;
Main.DispatcherTimer.Stop();
}
});
}

Server side there is no further action taken.

On client I get this:

16-32-18 11.32.04.005023 - Trying to connect to 127.0.0.1 on default port 5055...
16-32-18 11.32.04.021023 - Connection initialization in progress...
16-32-18 11.32.07.096023 - OnStatusChanged called with: Connect
16-32-18 11.32.08.130023 - OnStatusChanged called with: EncryptionEstablished

On server side I get:

The client freezes after the OpCustom that never gets to the server.

What am I doing wrong here?
