hallo there, i try send data to server use reliable channel but i got this message

Code (CSharp):

1. Channel {1} for connection {1} does not support fragmented messages; MTU: {1440}, message length: {2076}, max length {1402}
2. UnityEngine.Networking.NetworkTransport:Send(Int32, Int32, Int32, Byte[], Int32, Byte&)

this my code for config LLapi

Code (CSharp):

1. NetworkTransport.Init();
2.         ConnectionConfig cc = new ConnectionConfig();
3.  
4.         reliableChannel = cc.AddChannel(QosType.Reliable);
5.         unReliableChannel = cc.AddChannel(QosType.Unreliable);
6.         unreliableFragmenChanel = cc.AddChannel(QosType.UnreliableFragmented);
7.  
8.         HostTopology topo = new HostTopology(cc, MAX_CONNECTION);
9.         hostId = NetworkTransport.AddHost(topo,0);
10.         ConectId = NetworkTransport.Connect(hostId,ipServer,port,0, out error);
11.  
12.         connectionTime = Time.time;
13.         isConect = true;

i never connect to my server, if i dont use unreliableFragmenChanel can connect to server

 

According to the error you're trying to send a message larger than the max size for the channel.
