WCF / ASMX :: System.Net.WebException - "The Operation Has Timed Out"

May 3, 2010

I know this has been asked umpteen times but i cant find an answer to my problem. Very simply, i have a webservice client which is trying to call a webservice. The webservice may take any time from 5mins to 30mins (or more) for downloading message data from pop3 server . However after 2mins i get the following error:

System.Net.WebException: The operation has timed-out

This is an issue with the webservice client timing out calling the webservice - as the underlying webservice still runs in the background
Sequence osf steps when the error occurs:

1.User logins with his credentials
2.Webservice client calls webservice to connect to pop3 server and download messages for that particular user.

Code in webservice for downloading data from pop3 server where the exception occurs

private string ReadOutput(bool bMultiline)
StreamReader srReader = new StreamReader(conn);
string strRet = srReader.ReadLine();
if (bMultiline)
// Example #4: Append new text to an existing file
string strLine = "";
while (true)
// In a multiline message the . indicates end of message
if (strLine == ".")
// Relay will convert any line with just a . in it to ..
if (strLine == "..")
strLine = ".";
strRet += "
" + strLine;
return strRet;
catch (Exception e)
return null;

3.Exception is caught in webservice client while webservice continues to run.This exception occurs only when the user receives a large message may be above 1mb because i tested with 1MB msg file where i dint have any problem receiving or downloading from
pop3 server where as with 5 MB message file i got this exception .

After going through couple of forums i tested my luck by changing web.config in both webservice and webservice client where i set the attribute of httpruntime Execution timeout to 300 seconds with no success <httpRuntime


I have this webservice client and webservice running on localmachine(OS-Windows Vista)

C# - Crawler Webresponse Operation Timed Out

May 18, 2010

I have built a simple threadpool based web crawler within my web application. Its job is to crawl its own application space and build a Lucene index of every valid web page and their meta content. Here's the problem. When I run the crawler from a debug server instance of Visual Studio Express, and provide the starting instance as the IIS url, it works fine. However, when I do not provide the IIS instance and it takes its own url to start the crawl process(ie. crawling its own domain space), I get hit by operation timed out exception on the Webresponse statement. Could someone please guide me into what I should or should not be doing here? Here is my code for fetching the page. It is executed in the multithreaded environment.

private static string GetWebText(string url)
string htmlText = "";

ADO.NET :: Getting Error - System.InvalidOperationException: Operation Is Not Valid

Mar 29, 2011

I am using static class to do every job related to Database. In this class Connection Object is static but i am creating command object in the method. I read a form post here [URL] about creating connection object local. If we do like that how can we use Connection pooling? There is an example code below.

I am creating a connection object with pooling (Validate Connection=True; Min Pool Size=10; Max Pool Size=200; Incr Pool Size=10; Decr Pool Size=5;). I am expecting to use connection pool by static connection object (this obje has a connection poll) with dynamicly created commands. Am I wrong? Sometimes i am getting "System.InvalidOperationException: Operation is not valid due to the current state of the object." error. Is it because static connectin object?

Cancel A Long Running Database Insert / Update Operation From UI When Operation Is Being Performed By A Windows Service?

Mar 7, 2010

in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.

WCF / ASMX :: "decryption Operation Failed" Exception When Calling Web Service

Dec 20, 2010

These types of exceptions always irritate me because they are almost impossible to reproduce consistently and have almost no documentation other than the cryptic error itself to have any idea on how to fix the problem. So I have a Windows Service that makes a call to a .asmx web service over https on a polled interval every 20 minutes. Once in a great while the following exception message is returned:

Message: The underlying connection was closed: An unexpected error occurred on a receive.

Inner Message: System.IO.IOException: The decryption operation failed, see inner exception. ---> System.ComponentModel.Win32Exception:

The specified data could not be decrypted --- End of inner exception stack trace --- at
errorCode, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest, Byte[] extraBuffer) at System.Net.Security._SslStream.ProcessFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at
System.Net.Security._SslStream.StartFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartFrameHeader(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest)
at System.Net.Security._SslStream.StartReading(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.ProcessRead(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.TlsStream.Read(Byte[]
buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)

So from reading the above message there was an error on receive and the data could not be decrypted. The does not occur consistently, so I don't have a good way of reproducing it. I also lack at low level messaging knowledge and I feel that this is the answer behind this exception; i.e. dropped packets and an incomplete message not appearing to be the same message as sent from the service or something. Any .asmx gurus out there that can give insight and possibly prevention suggestions for the above issue?

WCF / ASMX :: Exposing Data Contract Without Passing As Input Or Output Parameter For Any Operation Contract?

Sep 21, 2010

I have a method in wcf which returns stream of custom object. I need to deserialize this stream at client side, but my custom class which is exposed as data contract is not visible through client proxy. When I add a dummy operation contract which returns the custome object I am able to get this custom class. I dont want to write this dummy method as there are many such custom classes.

Is there any way to expose data contract without writing any operation contract that returns or accepts data contract type object?

WebException NotFound Received When Using Silverlight With MVC?

Jan 11, 2011

I'm not entirely sure how to explain this, but basically I am trying to use a Silverlight application hosted within an ASP.NET MVC application. I have a basic controller on the MVC side that contains a method which accepts some string parameter and returns an ActionResult (for the purpose of this program, that result is some Json data).

My problem arises when I handle the WebClient.OpenReadCompleted event within the Silverlight control. When the WebClient.OpenReadAsync method is called within this control, it successfully reaches the controller and then reports back to the relevant event handler as expected. However, when it is handled, the event arguments contain an error stating: "The remote server returned an error: NotFound.".

Previously, I have noticed this is caused when some part of my communication URL is incorrect - in this case it is not. From some Googling, I have also noticed that this is a generic error. As such, I'm rather stumped. To make matters more confusing, I use this exact same communication attempt in another part of the program, that retrieves an array of strings, and that works perfectly fine.

see the example code below (due to the nature of this program, I am unable to post the full code).

Silverlight Control
WebClient mClient = new WebClient();
public void RequestData()
mClient.OpenReadAsync(new Uri("http://localhost:51234/Home/GetData"));
mClient.OpenReadCompleted += new OpenReadCompletedEventHandler(mClient_OpenReadCompleted);
private void mClient_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
if(!e.Cancelled && e.Error == null) // <-- e.Error here is a WebException
var serializer = new DataContractJsonSerializer(typeof(Data));
Data data = (Data)serializer.ReadObject(e.Result);

MVC Controller - named HomeController and accessed with "Home"

public ActionResult GetData()
return Json(new Data(), JsonRequestBehaviour.AllowGet);

Note Here, Data contains three members of types; string, string and byte array. For the purpose of serialization, I have exposed all three members through public properties containing both get and set parts. I have also added a public constructor taking no arguments.


I've just tried the same bit of code with different data, and it works fine. I wondered if it was the size of the data (as the first attempt was with very large data), but I don't understand why that would matter if the call managed to hit the controller.

C# - WebException Could Not Establish Trust Relationship For The SSL/TLS Secure Channel

Dec 20, 2010

My company has developed a .NET web service and a client dll that uses that web service. The webservice is hosted on our server over ssl and the cert is provided and signed by GoDaddy. We have some clients in a hosted environment that are getting the following error message from the client dll when it tries to access our web service.

System.Net.WebException The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

Our fix has been to have them open IE on the server, which is a challenge in and of itself for a lot of the hosted services, and go to the WSDL url. IE then prompts them with a security alert dialog. It says the cert date is valid and a valid name matching the name of the page, but was issued by a company you have not chosen to trust. When they click Yes to proceed, the client dll can then succesfully connect to the web service and operate as normal. why GoDaddy would not have been in there valid publishers list? All of the servers we have running has GoDaddy as a valid authority. I'm guessing, for security reasons, they've uninstalled the authority for GoDaddy, but not totally convinced that there's not some other underlying issue.

Unfortunately, I haven't had much luck trying to recreate this locally. If I go into Internet Options and remove the GoDaddy authorities and hit our service, ssl works just fine. I go back into the list of publishers and GoDaddy gets put right back in. So my second question is, How the heck do you get rid of GoDaddy so I can get an invalid cert warning?

Okay, last question. Is there a way in code I can tell the web service to ignore invalid certs. I've seen some posts on doing this programatically with WCF but not old web services.

Exception - HttpWebResponse - How Can I Not Depend On WebException For Flow Control?

Jun 9, 2010

I need to check whether the request will return a 500 Server Internal Error or not (so getting the error is expected). I'm doing this:

HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "GET";
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
if (response.StatusCode == HttpStatusCode.OK)
return true;
return false;

But when I get the 500 Internal Server Error, a WebException is thrown, and I don't want to depend on it to control the application flow - how can this be done?
