Server don't call delegate SetConnectionEventHandlerfor OPENED and ACTIVE any more

[RichyP7]

Describe the bug

The IEC104 Server won't call the Connection Handler for the OPENED and Active ConnectionStates any more in the 2.3.0 release

To Reproduce

Register

   server.SetConnectionEventHandler(handler, null);

Usage

        private void handler(object parameter, ClientConnection connection, ClientConnectionEvent eventType)
        {
            logger.LogInformation("connection event ({type}): {adress}", eventType.ToString(), connection.RemoteEndpoint.Address.ToString());
            if (eventType == ClientConnectionEvent.OPENED) 
            {  //NOT FIRED ANYMORE 
                _connected = true;
            }
            else if (eventType == ClientConnectionEvent.ACTIVE)
            {  //NOT FIRED ANYMORE 
            }
            else if (eventType == ClientConnectionEvent.CLOSED)
            { //STILL WORKS
                _connected = false;
            }

        }

Expected behavior

The handler worked in 2.2.0. If there is a IEC104 Client connecting to the server i can find out if some client is still connected.

Priority

This is important but not urgent as nobody is forced to update.

Container

• OS: Windows/Linux

• Version Windows 11

• .NET Version: 10.0

Additional context

Client is using the same library and is already on version 2.3.0
