TCP connection problem.

[Anonymous]

Hi NetworkCommsDotNet,

– I am developing on IOS with Xamarin. I used NetworkCommsDotNet to connect my server. But it throw:
Timeout waiting for server connnectionInfo from [TCP] 127.0.0.1:49585 -> 127.0.0.1:8888. Connection created at 13:49:20.140, its now 13:49:30.2

– And my server log: MINA Input – sessionCreated on Thread: 19

– I do not understand why my server can create session, but in client it throw time out exception. Here is my code:

public void Connect (string ip, int port) 
		{
			Debug.WriteLine (TAG + " - Connect to ip: " + ip + " and port: " + port);
			this.IP = ip;
			this.Port = port;
			ConnectionInfo serverConnectionInfo = null;
			try 
			{ 
				Debug.WriteLine (TAG + " - Initing Connection Info");
				serverConnectionInfo = new ConnectionInfo(this.IP, this.Port);
				Debug.WriteLine (TAG + " - Inited Connection Info");
			}
			catch (Exception)
			{
				Debug.WriteLine (TAG + " - Failed to parse the server IP and port. Please ensure it is correct and try again.");
				return;
			}
			//We perform the send within a try catch to ensure the application continues to run if there is a problem.
			try
			{
				TCPConnection.GetConnection(serverConnectionInfo, true);
			}
			catch (CommsException e) 
			{
				Debug.WriteLine (TAG + " - " + e.Message);
				if (MessageHandler != null) {
					MessageHandler.OnConnectionFail ();
				}
				return;

			}
			catch (Exception) 
			{ 
				Debug.WriteLine(TAG + 
					" - Error: A general error occured while trying to send message to " + serverConnectionInfo + ". Please check settings and try again."); 
			}
			Debug.WriteLine (TAG + " - Connected to ip: " + ip + " and port: " + port);
			if (Session != null && MessageHandler != null) {
				MessageHandler.OnConnected ();
			}
		}

Please, give me some idea about that. Thanks.

Heya truongps,

Many kind thanks for your interest in our network library and welcome to our forums. What version of the library are you using?

“127.0.0.1” is a loopback address and can only be used if your client and server are on the same machine. Please try connecting to your server using a different IP address.

Regards,
Marc

Hi MarcF,

– I get NetworkCommsDotNet from Xamarin Component Store.
– I run my server on local, my client and server are on the same machine. So the server ip is: 127.0.0.1. And it throw this. My server based on Apache Mina.

Thanks for your attention,

Heya TruongPS,

The version of NetworkComms.Net on the xamarin component store is 2.3.0, which is over a year old. Could you please test using version 3.0.0 to see if you still have this problem?

Regards,
Marc
