Help/Problem timeout sendandwait

[philipphagen87]

Hello,

I really need help with the Server/Client.. My Configuration of the Server is

public static class AsyncServer
    {
        private static string serverIp = "10.0.0.46";
        public static int ServerPort = 9000;
        private static bool useSsl = false;
        private static WatsonTcpServer server = null;
        private static string certFile = "";
        private static string certPass = "";
        private static bool debugMessages = false;
        private static bool acceptInvalidCerts = true;
        private static bool mutualAuthentication = true;

        public static void ConfigServer()
        {
            server = new WatsonTcpServer(serverIp, ServerPort);
            server.ClientConnected += ClientConnected;
            server.ClientDisconnected += ClientDisconnected;
            server.MessageReceived += MessageReceived;
            server.SyncRequestReceived = SyncRequestReceived;
            // server.PresharedKey = "0000000000000000";
            // server.IdleClientTimeoutSeconds = 10;
            logger.Info("Server configuration done");
        }

        public static void StartServer()
        {
            Task serverStart = server.StartAsync();
        }

My client:

public static class AsyncClient
    {
        public static  string ServerIp { get; set; }
        public static int ServerPort { get; set; }
        private static bool useSsl = false;
        private static string certFile = "";
        private static string certPass = "";
        private static bool debugMessages = false;
        private static bool mutualAuthentication = true;
        private static WatsonTcpClient client = null;
        private static string presharedKey = null;

        public static void ConfigClient()
        {
            client = new WatsonTcpClient(ServerIp, ServerPort);
            client.ServerConnected += ServerConnected;
            client.ServerDisconnected += ServerDisconnected;
            client.MessageReceived += MessageReceived;
            client.SyncRequestReceived = SyncRequestReceived;
        }

        public static void StartClient()
        {
            try
            {
                Task startClient = client.StartAsync();
            }
            catch (Exception ex)
            {
                logger.Error("Could not connect to server: {0} Port: {1}", ServerIp, ServerPort);
            }
        }

I want to SendAndWait:

public static void SendAndWait()
        {
            int timeoutMs = 20000;
            string userInput = "testingstring";
            try
            {
                SyncResponse resp = client.SendAndWait(timeoutMs, userInput);
                if (resp.Metadata != null && resp.Metadata.Count > 0)
                {
                    logger.Info("Metadata:");
                    foreach (KeyValuePair<object, object> curr in resp.Metadata)
                    {
                    }
                }
            }
            catch (Exception e)
            {
            }
        }

At server side

private static SyncResponse SyncRequestReceived(SyncRequest req)
        {
            if (req.Metadata != null && req.Metadata.Count > 0)
            {
                logger.Info("Metadata:");
                foreach (KeyValuePair<object, object> curr in req.Metadata)
                {
                    logger.Info("  " + curr.Key.ToString() + ": " + curr.Value.ToString());
                }
            }
            Dictionary<object, object> retMetadata = new Dictionary<object, object>();
            retMetadata.Add("foo", "bar");
            retMetadata.Add("bar", "baz");

            return new SyncResponse(req,retMetadata, "Here is your response!");
        }

It is the same sample as stored in git. If i download the current version from git and test ist, everything is fine. But if i do the same thing with the code above I always get the timeout exception (no msg received after timeout) If i debug then the server recognize the incomming msg and work and "send" back.

Can anybody help me?

nice greetings phil

What is your version of WatsonTcp? This bug was fixed in 3.1.3, although exists when the server sends a sync request to the client.

[philipphagen87]

Sorry i forgot to write that i also tried with V3.1.3

[developervariety]

No problem, so you are sending a sync request from the server to the client correct?

[philipphagen87]

From the client to the Server

[developervariety]

Client -> Server is working completely fine on my end. That's odd! It's only Server -> Client is the problem for me.

Hi @philipphagen87 are the client and server running on the same machine or different machines?

[philipphagen87]

they are running on the same machine

[jchristn]

Can you send any messages back and forth using other Send APIs?

Could you package your solution up and share it with me and I'll take a look?

Cheers, Joel

Hello @philipphagen87 , were you able to get this working? Or able to package up a portion of your solution for me to examine?

[philipphagen87]

Sorry for the late answer... i fixed my problem.. it was my architecture! thanks for support..

[jchristn]

Awesome thanks @philipphagen87 please let me know if I can help in the future.
