WatsonTCP on Windows 11, not connecting

[Mudoch]

I'm having an issue with Server side not responding to Connection requests under windows 11, however the same code responds under windows 10. Checked firewall and everything looks good. Tried running the app as admin under windows 11 too same result.

I getting the message timeout trying to connect to ip address did not respond in time.

Again same code (exe) is running fine under windows 10.

Any ideas on what I'm missing?

.net 6.0 app, watsontcp version 4.8.14.14. Tried to update to latest version but there I get breaking changes with WatsonTCP

private static WatsonTcpServer _Server;

  _Server = new(null, _serverPort);
  _Server.Events.ClientConnected += ClientConnected;
  _Server.Events.ClientDisconnected += ClientDisconnected;
  _Server.Events.MessageReceived += MsgReceived;
  _Server.Callbacks.SyncRequestReceived += SyncRequestReceived;

  _Server.Settings.DebugMessages = false;
  _Server.Start();
