The remote server returned an error: (400) Bad Request

I am getting the following errors:

"The remote server returned an error: (400) Bad Request"

"Requested time out"

sometimes when connecting to a host using a web service. If the XML returned is 5 kb then it is working fine, but if the size is 450kb or above it is displaying the error.

Below is my code as well as the config file that resides at the client system. We don't have access to the settings of the server.

 Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim fileName As String = Server.MapPath("capitaljobs2.xml")

        Dim client = New CapitalJobsService.DataServiceClient("WSHttpBinding_IDataService", "http://xyz/webservice.svc")


        Dim userAccount = New UserAccount()

        'replace here 
        Dim jobAdList = client.GetProviderJobs(userAccount)

        '## Needed only to create XML files - do not ucomment - will overwrite files 
        'if (jobAdList != null) 
        ' SerialiseJobAds(fileName, jobAdList); 

        '## Read new ads from Xml file 
        Dim capitalJobsList = DeserialiseJobdAds(fileName)
        UpdateProviderJobsFromXml(client, userAccount, capitalJobsList)              
        client.Close()
    End Sub

 Private Shared Function DeserialiseJobdAds(ByVal fileName As String) As CapitalJobsService.CapitalJobsList
        Dim capitalJobsList As CapitalJobsService.CapitalJobsList
        ' Deserialize the data and read it from the instance 
        If File.Exists(fileName) Then
            Dim fs = New FileStream(fileName, FileMode.Open)
            Dim reader = XmlDictionaryReader.CreateTextReader(fs, New XmlDictionaryReaderQuotas())
            Dim ser2 = New DataContractSerializer(GetType(CapitalJobsList))
            capitalJobsList = DirectCast(ser2.ReadObject(reader, True), CapitalJobsList)
            reader.Close()
            fs.Close()
            Return capitalJobsList
        End If
        Return Nothing
    End Function

And the config file

    <system.serviceModel>
        <bindings>

                                <identity>
                    <dns value="localhost"/>
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>

I am using "Fiddler" to track the activities it is reading and terminating file like

* FIDDLER: RawDisplay truncated at 16384 characters. Right-click to disable truncation. *

But in config the number 16348 is not mentioned anywhere.

Can you figure out if the error is on client or server side? The settings above are on the client side.

Thanks in advance.

Maybe you can increase the timeout of call like suggest in this thread Setting Timeout Value For .NET Web Service
