Stop players from connecting to a LAN session

I’m using the online session blueprint nodes to create my game session (LAN). Everything is working fine but i want to stop people from joining after the game has started (I determine at what point to stop people from connecting). Is there anyway to do this with the session nodes? I tried to use DestroySession on the server but it kicks the clients out. According to the docs

Also how do i have players reconnect (game crashed or computer restarted) if i do stop connecting after the game has started.
