System.Net.WebE xception: The operation has timed out

[DBC User]

Hi,

I have a web client code written in C# and I am using web services
using the proxy created by VS2005. Only timeout I am using this case
is the SOAP envelop timeout. When I run the code it is keeping timing
out. Could someone tell me what could be the reasons? [One side note a
new server is added to the pool and this code didn't change for couple
of months and its been working properly till a week ago, there is
nothing changed during that week though]. Here is the code snippet
that is failing

private void CIn()
{
taskComplete = false;

ServiceWse wse = new ServiceWse();
wse.UseDefaultC redentials = false;
SoapContext ctx = wse.RequestSoap Context;
ctx.Security.To kens.Add(token) ;
ctx.Security.El ements.Add(new MessageSignatur e(token));
ctx.Security.Ti mestamp.TtlInSe conds = _Timeout;
AppSettingsRead er config = new AppSettingsRead er();
Uri dest = new
Uri(config.GetV alue(ReferenceN ames.WebService URI,
typeof(string)) .ToString());
Uri via = new Uri(config.GetV alue(WSELocatio n(),
typeof(string)) .ToString());
ctx.Addressing. Destination = new EndpointReferen ce(dest,
via);

byte[] fileContents = File.ReadAllByt es(aDirectory =
zFileName);
try
{
wse.CIn(a, y, t, x, R, fileContents);
taskComplete = true;
}
catch (System.Web.Ser vices.Protocols .SoapException e1)
{
log.Fatal(" failed " + e1.ToString());
}
catch (Exception e1)
{
log.Fatal(" failed " + e1.ToString());
}
}
else
{
log.Fatal("Unab le to file");
}
}
