    Hi,

    could you please confirm that you are still using the SDK for .NET Adapter version 1.7 on remote side?
    Is there any chance to get the log file of remote adapters?

    Thanks
    Gianluca

    I was talking about .NET adapter log file, if any.

    Hi,

    the log you sent us is full of issues due to "notifyUser" invocation, as follows:

    20-أبر-15 11:38:42,170|ERROR|LightstreamerLogger.requests |ET DataPool POOLED THREAD 3|Unexpected error in notifyUser: Timeout while waiting for an answer to request 30000014cd5fa8421:

    Do you have any chance to monitor such invocation on .NET adapter? Is your notifyUser somehow related to any external system which could provoke any timeouts?

    Regards,
    Gianluca

    i can't understand you
    my problem is in connection to LS despite the port 8080 is opened
    the exception is in client1.OpenConnection() :
    An unhandled exception of type 'Lightstreamer.DotNet.Client.PushConnException' occurred in DotNetClient_N2.dll


    Additional information: The remote server returned an error: (500) Internal Server Error.


    this is the code for connecting:

    ConnectionInfo _cInfo = new ConnectionInfo();
    _cInfo.PushServerUrl = "http://localhost:8080";
    _cInfo.Adapter = "DataPool";


    LSClient client1 = new LSClient();
    client1.OpenConnection(_cInfo, new Tabee3ConnectionListener());

    Hi,

    the (500) Internal Server Error is due to a communication problem between Lightstreamer Server instance and the remote .NET Adapter.
    The .NET Adapter is experiencing an issue in notifyUser method, remotely invoked by the Lightstreamer Server, which in turn raises an Internal Error.
    Probably you have overridden the notifyUser method in your Adapter to perform some authentication logic and there a problem occurs.

    Please verify that logic and get back to us.

    Regards,
    Gianluca

    hello,
    my adapter was working well at LS version 5.2
    but why now gives that Exception

    this is the adapter class

    Code:
        class IntraDayAdapterUpdate : LiteralBasedProvider, IDataProvider
        {
    
    
            private IItemEventListener _listener;
    
    
            public void Init(System.Collections.IDictionary parameters, string configFile)
            {
          
            }
    
    
            public bool IsSnapshotAvailable(string itemName)
            {
                //throw new NotImplementedException();
                return true;
            }
    
    
            public void SetListener(IItemEventListener eventListener)
            {
        
                if (Intraday._listener == null)
                    Intraday._listener = eventListener;
            }
    
    
            Intraday obj;
            public void Subscribe(string itemName)
            {
    
    
        
            }
    
    
            public void Unsubscribe(string itemName)
            {
    
            }

    This is really puzzling, as the Proxy Adapters for Server 6.0 with "init_remote" configured to false should behave exactly like the Proxy Adapters for Server 5.1.2, so nothing was supposed to change for the remote part.
    Since the remote NotifyUser is empty and cannot be responsible for delaying the response, we must find some error message in the log of the remote process.

    Do you see anything in the remote process console?
    Perhaps we have to configure the log properly.
    As a preliminary step, please clarify if you run the Remote Metadata Adapter by taking advantage of the supplied DotNetServer_N2.exe or if you use a custom executable (possibly based on the supplied "StandaloneLauncher.cs" example).

    i can't understand your question about the remote metadata adapter
    no thing clear to me other the exception of the connection to LS
    and that was working well at the version 5.2
