Our site is down and I don't know what to do here. Any ideas are most welcome.
Try increasing the SendTimeout and ReceiveTimeout properties in service/client configurations.
WCF Service , how to increase the timeout?

I've written a WCF service hosted on server 1. I can call it successfully from my local pc, but when I try to call the same function from server 2. it shows below error:
One or more errors occurred. (A connection attempt failed because the
connected party did not properly respond after a period of time, or
established connection failed because connected host has failed to
respond.
my code is:
var client = new Sepidar_WcfService.SepidarClient();
Task<Sepidar_WcfService.ISepidarServiceOutput> tStocks = client.GetStocksAsync("1", "1");
the stack trace is:

any help would be appriciated!
I found the problem, The problem is, I try to call the WCF service with http, while service client has https protocol. Thus the issue is related to "same origin policy" concept.
I am trying some edge cases in my software. So I have created a very simple test environment:
RabbitMQ server running on CentOS 7
Message consumer written against .NETCore 2.1 in C# running under CentOS 7
Message sender written against .NETCore 2.1 in C# running under CentOS 7
I send a simple text message every 5 seconds. The sender and receiver run on the same UNIX box, while the RabbitMQ server runs on a different machine in the network.
So far so good. Now I stop my RabbitMQ server with systemctl stop rabbitmq-server.
I get errors on the sender and the receiver which was expected.
I restart the RabbitMQ server using systemctl start rabbitmq-server.
And now the fun starts! The sender can recover and continues to send messages but the consumer CANNOT recover and does not receive messages. They are accumulated on the RabbitMQ server!
Here are my log entries from the sender (which works as expected):

This shows the last error message and then one can see that EasyNetQ recovered and can deliver messages again.
The message consumer does NOT work! Here my log entries:

Here it sits and waits forever! Looks like the thing is deadlocked in a way while the messages are accumulating on the RabbitMQ server:
When I stop my consumer application and restart it, the messages are picked up.
I connect in both applications (sender and consumer) with the following code:
private static IBus SetupRabbitMqConnection(string rabbitServer, string rabbitVHost, ushort rabbitPort, string rabbitUser, string rabbitPwd)
{
Log.Logger.Debug($"Creating a connection to RabbitMQ server '{rabbitServer}' on port {rabbitPort.ToString()} " +
$"using the EasyNetQ library....");
try
{
var connStr = $"host={rabbitServer}:{rabbitPort.ToString()};virtualHost={rabbitVHost};username={rabbitUser};" +
$"password={rabbitPwd};publisherConfirms=true;timeout=30;prefetchcount=1;requestedHeartbeat=30";
var msgBus = RabbitHutch.CreateBus(connStr, x => { });
if (!msgBus.IsConnected)
{
var errMsg = $"Currently not connected to RabbitMQ server '{rabbitServer}'.";
Log.Logger.Error(errMsg);
}
Log.Logger.Debug("Successfully connected to RabbitMQ server.");
return msgBus;
}
catch (Exception ex)
{
Log.Logger.Error($"Error to establish a connection to RabbitMQ server '{rabbitServer}'. Error: {ex}");
throw;
}
}
The consumer program registers the listeners as follows:
var msgBus = SetupRabbitMqConnection(rabbitServer, vhost, rabbitPort, rabbitUser, rabbitPwd);
RegisterMsgSubscriptions(msgBus);
private static void RegisterMsgSubscriptions(IBus msgBus)
{
Log.Logger.Debug("Starting to register RabbitMQ message subscriptions...");
try
{
#region Queue declarations
var advancedBus = msgBus.Advanced;
var testQueueOne = new EasyNetQ.Topology.Queue(TestQueueOneName, true);
Log.Logger.Debug("Finished declaring queues.");
#endregion
#region Message Queue Handler registrations
advancedBus.Consume(testQueueOne, registration => registration
.Add<RabbitMessage<TestTextMessageDto>>(MessageProcessor.ProcessRabbitTestMessage));
Log.Logger.Debug("Finished registration of message handlers for several queues.");
#endregion
}
catch (Exception ex)
{
Log.Logger.Error($"Error registering message handler. Error: {ex}");
}
}
Any idea what might go wrong here?? In production we have more than 100 servers consuming messages. These servers are on premise spread all over the country. The RabbitMQ server is in the data center. So the consuming servers MUST recover if the connection gets lost, otherwise this is not usable!
Just add subscription logic on connected event (It will be fired on every broker connected event).
advancedBus.Connected += (sender, args) => {
// subscribe logic
};
Of course You should handle not to call subscribe logice twice on any connect etc.
We have a Windows Service which uses WCF to reads messages from an MSMQ queue. Recently, the service won't start because it can't open the queue:
Running WcfHost, service contract IWcfService. :

that MSMQ is installed and running, the queue exists and has proper authorization

We've double-checked the queue's permissions and they haven't changed. We've run ProcMon and aren't seeing any access denied events. We don't know what changed to cause this error.
Why can't WCF open this queue?
You can try turn off RPC request from queue settings?
I am writing WCF client for service writtern in Java by one of the partner. I am getting an exception when I make first service call to thier service. But subsequent request did not throw any exception. I am using console application to test this. Why is that failing on first time not other times?
Here is code how I am calling the service multiple times

I fixed this error by setting KeepAlive property to false. What I found was happened, when first request sent to the service endpoint, got 401 response from server (it is obivous because service using the basic authontication and then client sent basic authorization header in next request) that closes the connection. Default behaviour of client endpoint is to keep the connection alive. Though connection closed, client still send next request by using the same connection that already closed by the server that causes the above said error in the question. But this error won't happen again for subsequent requests because client send request with authorization header in the first request itself. So there is no chance of 401 response. What I did to fix this issue that set Keep alive property to false. So that, after 401 response, client send another request with new connection instead of using the old connection. Here is code
Binding binding = null;
var transportElement = new HttpsTransportBindingElement
{
AuthenticationScheme = AuthenticationSchemes.Basic,
KeepAliveEnabled = false,
};
var messegeElement = new TextMessageEncodingBindingElement
{
MessageVersion = MessageVersion.CreateVersion(EnvelopeVersion.Soap11, AddressingVersion.None),
ReaderQuotas =

MaxArrayLength = 200000,
MaxBytesPerRead = 200000,
MaxDepth = 200000,
MaxNameTableCharCount = 200000,
MaxStringContentLength = 200000
}
};
binding = new CustomBinding(messegeElement, transportElement);
return binding;
I use the WCFTestClient that is provided with visual studio to test my service.
The thing is that the tool is working for the service that is deployed in wisual studio with my aplication. But if I try to connect to a deployed instance on another machine I get the following exception. Has anyone solved this issue?
The service uses WindowsAutentication.
The HTTP request is unauthorized with client authentication scheme 'Negotiate'.
