Cannot Reconnect to server after disconnect

[roozb]

I'm using Lidgren to connect a unity game to my gameserver. everything works fine. the only problem is when the client disconnects from the server (by loss of internet connection or even manually) it cannot connect again. I have to close and reopen the game to be able to connect again. I have tried this outside the unity too and got the same results:

    client.Connect();  // successfully connects to the server

    wait 1 sec

    client.Disconnect(); // client gets disconnected

    wait 1 sec

    client.Connect(); // server has no reaction to this

Is there something I am missing?
