Trouble with LLAPI

I've searched for a good while now and I couldn't find an answer for this. I'm trying to send a message from the client to the server at start. Whenever I do so, the client error byte is set to 2 andd the message doesn't make it. Here's the client code:

 public void Connect()
     {
         byte error;
         mainConnectionId = NetworkTransport.Connect(mainHostId, "127.0.0.1", socketPort, 0, out error);
 
         NetConnected msg = new NetConnected();
 
         SendMessage(msg);
     }
 
     public void SendMessage(NetMessage msg)
     {
         byte error;
         byte[] buffer = new byte[maxBufferSize];
 
         Stream stream = new MemoryStream(buffer);
         BinaryFormatter formatter = new BinaryFormatter();
         formatter.Serialize(stream, msg);
 
         NetworkTransport.Send(mainHostId, mainConnectionId, reliableChannelId, buffer, maxBufferSize, out error);
 
         Debug.Log("Send error " + error);
     }

and the server:

 public void UpdateMessagePump()
     {
         byte[] buffer = new byte[maxBufferSize];
         NetworkEventType recType = NetworkTransport.Receive(out int hostId, out int connectionId, out int channelId, buffer, maxBufferSize, out int receivedSize, out byte error);
 
         switch (recType)
         {
             case NetworkEventType.Nothing:
                 break;
 
             case NetworkEventType.ConnectEvent:
                 Debug.Log("User connected.");
                 break;
 
             case NetworkEventType.DisconnectEvent:
                 Debug.Log("User disconnected.");
                 break;
 
             case NetworkEventType.DataEvent:
                 Debug.Log("Recieved data.");
 
                 BinaryFormatter formatter = new BinaryFormatter();
                 Stream stream = new MemoryStream(buffer);
 
                 NetMessage msg = formatter.Deserialize(stream) as NetMessage;
 
                 OnData(msg);
 
                 break;
         }
     }
 
     public void OnData(NetMessage msg)
     {
         switch (msg.messageType)
         {
             case NetMessageType.Invalid:
                 Debug.Log("Unexpected message type");
                 break;
 
             case NetMessageType.Connected:
                 Debug.Log("Connected msg.");
                 break;
         }
     }

As you can see, the connection id is set just above the call of the method Send(). I don't understand unity's networking system that well but its the second time I try to implement this sort of thing and I got the same result before. Any help would be appreciated. Thanks in advance. Sorry if my english is incorrect.

Also, if you want, I can post the whole code for both server and client.
