		KeyPair client_static_keypair = null;
		PublicKey server_static_key = null;
		WA4Protos.ClientPayload payload = null;

		//Create connection
		Connection conn = new Connection("g.whatsapp.net",443)
			.setEdgeRoutingInfo(edge_routing_info)
			.setS(client_static_keypair)
			.setRS(server_static_key)

register注册成功后，运行Main.java函数，在握手函数中服务器返回了null,我用的翻墙软件

在Connection.java的 140行,byte[] server_hello_data = in.readSegment();这个server_hello_data是null，服务器没有返回数据，是因为翻墙软件导致的吗
