The Remote Host Closed The Connection. The Error Code Is 0x80070057?
Aug 19, 2010
I'm getting a lot of these error messages in my logs on one of my servers and intermittently on two others.Googling didn't reveal very much information, mostly related to file uploads or downloads being interrupted. My pages are basically just text files with "ok" in them that only have .aspx extension for future plans, there's no actual code powering the pages. Servers are all Windows Server 2008 RC2 x64 running IIS7 / ASP.NET 4.Statistically it's happening well under 1% of the time but because of the volume of traffic that still clutters my event log with 2 or 3 of these messages per minute.Edit:tracked down the problem, setting buffering to true stopped it occurring.
I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
I have created a webservice in 2010. And when I call it from my web application sometimes,It generates the follwoing errors:-1. The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.2. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.I have already tried increasing excutonTimeOut etc.
This error stopping my work in my crucial time. The error is "The underlying connection was closed: The connection was closed unexpectedly.".There are multiple WCF service I created in my project. But when I am requesting only one service this error is coming. I compare with other service, no difference. The service works fine in the morning, but afternoon it stops working and raising error.
I installed Silverlight 3.0 Tools for 2008 Sp1, Silverlight 3.0 Developer, WCF RIA Beta and Silverlight 4.0 runtime in my system in the morning. After getting this error I uninstalled WCF RIA Beta. But same issue.Could not find any solution. Please assist me how to solve this issue.
I'm receiving the following error occasionally when calling web service using a .NET 4.0 web application."The underlying connection was closed: An unexpected error occurred on a send."All of the articles I've read regarding this issue are for the Framework 1.1.Is there any solution to this issue for using .NET framework 4.0?
I am consuming a third party web service wsdl using my .net aps.net page. And I am getting following error message. Cannt get to resolve it. Its working on my machine but not in my development machine. I have installed the certificate also in certificates on that machine.
Error --> The underlying connection was closed: An unexpected error occurred on a send.
I have my wcf service and it runs fine. Then from my asp.net application I am trying to connect to this service. Everything is ok, request from asp.net is received in service (as I can debug code) and then when it returns to client I have the following error:underlying connection was closed: The connection was closed unexpectedlyMy contract on WCF service is as follows:
And WCFResponseGetAllProducts , WCFRequestGetAllProducts classes have [DataContract] attributes. Members of those classes have [DataMember] attribute. However when I added another method to my contract:
[OperationContract()] int Test();
then I can execute it from asp.net mvc application without a problem. PS. I host my wcf service in default web server in visual studio 2010 at the moment
I have a WCF service which has 4 Operation contracts.
I have added a new contract and it gets the data from database and returns the result set.
I can access the new contract and the service get the correct result set. But while passing the result set to the client I get the error of The underlying connection was closed: The connection was closed unexpectedly.
What are the steps to follow after adding a new contract like new binding etc.
Im working with this Arquitecture : Web Service -> DLL(Xml Translator) -> Asp.net.Everything works fine, but,i have a process that takes about 23 minutes, in that time i show a "loading screen" that avoid the user to do anything, but after 20 mins while the web service is working and after debug my code, i get this error :
"The underlying connection was closed: The connection was closed unexpectedly"
Then, my "loading screen" keep visible until the web service completes the work, and after that, the "loading" hides and the web form shows my gridview empty.(its should show data).
In Visual Studio 2005 I am following the steps to add a Web Reference to a web service.hings appear to go smoothly except for an error messae I am getting. Here are thesteps I follow along with the result.1. Right click on Web References folder and select "Add Web Reference..."2. When the dialog box appears I add the web service URL into the URL dialog box.The web service methods are then displayed in the dialog box with the links to each web service and a prompt to "Start Browsing for Web Service"However in the box to the right which is labeled "Web services found at this URL", there is an error messagewhich reads:There was an error downloading 'https://stage-serv/weatherQuote/WebService/weatherQuote.asmx
The underlying connection was closed: An unexpected error occurred on asend.Authentication failed because the remote party has closed the transport stream.I don't know what is causing this problem. I can reference this same web service on a productionserver just fine, but if I attempt to access it on the stagig server I get the message Ijust talked about.I am thinking that something is not configured on the staging server correctly.
Now, these two operations are done with two different connections (say con1 and con2). Both these connections are enlisted in the same TransactionScope.
Before the delete/insert operations the connections are opened and immediately closed.
So, now if the insert fails, then how is the delete rollbacked since con1 has been closed?
I have a Silverlight 3 application. It accesses WCF services that run on IIS. If I let the application sit for a while with no activity, it appears that I lose my connection to the server/login authentication, and my service calls fail.
It would appear that I am being logged out for security purposes, but this is not an area that I understand well. We are using a federated STS to create an encrypted token for security.
Can someone explain what is happening (if my description is clear enought), and how can I detect this event in my Silverlight application and redirect them back to the login page.
I have a web application which runs perfectly in my local machine. But the same when hosted in server, for some pages (which gets large amounts of data) gives me:-
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.-- in chrome Server not found-- in firefox
and Internet Explorer cannot display the webpage-- in IE
I went through lot of other forums and some were suggesting to put this is web.config file
I heve been sent some code as an example (BELOW in C#) with a login password, to request data from a remote site.
For example: A customer is givn a code from a remote site that contains his data. the customer then arrives at my site enterst the code on my sites form the script access the data from the remote site.
e.g. A customer enter my site > enters code> collects data from remote server> displays on my site> proceeds to checkout on my site.
I have no idea how to do this from the code example.
Code:using System; using System.Collections.Generic; using System.Text; using System.Xml;
I'm getting the "The underlying connection was closed: The connection was closed unexpectedly." error while trying to POST using the HttpWebRequest class on the production server, on my dev machine it works fine.
I originally tried using the WebClient class but I switched to the HttpWebRequest to try some of the suggestions I found while researching the issue (such as setting KeepAlive to false, PreAuthenticate true and ProtocolVersion to 1.0).
Since it's only happening on the production server, i'm guessing that it might have something to do with IIS.
Here's my code

If set the Target Framework (I used a new project for testing) to 2.0 (I didn't test every version of the framework) it works. I'm guessing that .net handles the security differently in .net 4.0.
i bind a dropdownlist to a database and later on, on button click i connect to database to get some value in a label. My 1st part works fine but when i try to do the second part i get the error message as

I'm getting an error in Parallels Plesk for SQL Server database on restore the cause of which is a mystery to me. Here is the support ticket I sent my hosting company:
I'm in the process of restoring my databases and the first one restored just fine. The second one called ***** for *****.com failed with the following error:
Error: dbbackup failed: Unable to restore database 'alienreports' Not valid backup The media family on device C:WINDOWSTEMPlocalhostalienreports*******.bak' is incorrectly formed. SQL Server cannot process this media family. VERIFY DATABASE is terminating abnormally.
This happened both when using the .bak file from my old host and after restoring that file on my local machine using SQL Server Management Studio 2008 just fine before backing it up and getting the same error when trying to upload and restore.
We have a virtual server hosted to the third party which we access through remote desktop. We have Sql server 2008 on Windows 2008. I created a website on my local hard drive and now we are ready to deploy. My question is what are the recommendations for publishing websites? What steps I need to take care of? Is it possible not to deploy the "code-behind" files. Incase of hacking of windows server, I do not want somebody to see my .vb files or Is it possbile that I can convert the whole thing except aspx files in to a strong dll?
I have a website that was originally written in webforms to which I have added MVC functionality. When debugging locally it works fine, however, once published and uploaded to my host the routes do not work and return a 404. I am pretty sure that I have uploaded all the correct files. Would just appear that routing is not working.
(the site will still serve normal aspx pages fine)
I think the problem may be related to http://stackoverflow.com/questions/1772975/mixing-asp-net-mvc-into-asp-net-webforms
But I cant see from that thread what the solution was. It looks like it might be something to do with the app_pool mode - but I am running in integrated mode, which is right AFAIK
UPDATE 2
So I think I have routing working. I basically created a new MVC app and went through theweb config file line by line and made sure I have everything I needed. Funnily, none of the tutorials online mention the correct additions you need to make. I have have another issue mind you... When i load my mvc page I am greeted with the message: The SessionStateTempDataProvider requires SessionState to be enabled.
I've added a line to web.config to enable sessions (wasn't aware they were off) and it still doesnt work.
UPDATE I created a new asp.net MVC project and ended up going through web.config line by line and ensuring that everything that related to MVC was included in my hybrid app. Suffice to say that none of the guides mention all the settings that are required (i was using the book professional asp.net mvc 1.0). I then included the global.asax file which is not published and set up a route so that a request for / was not being caught by MVC. I also had to enable sessions in web.config.
I'm trying to implement a bit of functionality that will behave much like the CustomError pages: if the connection is remote function A() will run; else function B() will run. The only problem I'm having is that I'm not sure the best way to determine a "remote" connection. Does it matter if I'm running my code on a shared web host? Can I rely on just comparing "my" IP to the request's IP?
In my asp.net +vb+access web i have made a login page and the code is as under
Dim connectString As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:webauth.mdb" Dim con As OleDbConnection = New OleDbConnection(connectString) con.Open() Dim cmd As New OleDbCommand("select * from Users where userid =@userid and Password=@password", con) cmd.Parameters.AddWithValue("@userid", txtUserName.Text)
[Code] ....
I am getting error The connection was not closed. The connection's current state is open.
