The operation has timed out error

TradeM

Hello,
While using .net client App, i have started getting "'The operation has timed out." error recently. Any idea what could be cause for this? There is no network issue here.

tonystark

The above error message is not thrown by the library exceptions. It must be from the .Net framework or by the system.

Please post exception stack trace or a code snippet that can reproduce the issue at our end. It is difficult to pinpoint the issue just from an error message.

Please see below. Do you think this could be due to certain windows security updates? My system did install few updates recently

This seem like a network timeout. Program is unable to initiate a connection to Kite even after a long time.

I'm unsure if security updates can cause this. But if there was any changes to your network/firewall/internet/DNS settings then this can happen. Couple of things to try:

1. Try opening https://api.kite.trade/ in browser. If this loads then it is not internet issue.
2. Try `ping api.kite.trade` in command prompt. If this works then your DNS is fine.
3. Try a new sample project and see if that is able to access Kite data. If this works then your firewall has blocked your main program.

1 & 2 are fine. I have put all firewall settings off.

Also, i am getting below error intermittently. Any thoughts? I am clueless as to why i started getting these errors from last couple of days.

And remember, these are happening randomly. The same GetLTP API works fine sometimes and throws "Operation was cancelled" / "Operation time out" errors other times.

tonystark

From the documentation it looks like `OperationCanceledException` is pretty much same as timeout exception.

TradeM

What do you mean by these exceptions are pretty much same? There got to be different logic when two different exceptions are raised.

tonystark

I meant they seem to trigger due to the same reasons. And they are hard to distinguish. Ref: https://stackoverflow.com/questions/35615638/any-way-to-differentiate-cancel-and-timeout

Hey tonystark,
My user ID is PJR394. Now I am continuously getting time out error.. here is call stack. Any help you could provide is much appreciated.
I downloaded fresh kiteconnect sample from github.. changed network etc. to eliminate that possibility. No luck.

This exception was originally thrown at this call stack:
[External Code]
KiteConnect.Kite.Request(string, string, dynamic, System.Collections.Generic.Dictionary, bool) in Kite.cs

TradeM

Here is piece of code that throws time out exception:

try
{
webResponse = request.GetResponse();
}
catch (WebException e)
{
if (e.Response is null)
throw e;

webResponse = e.Response;
}

tonystark

If the sample code itself is throwing the error then I'm out of ideas.

May be you should try in a different machine while being in the same network. See if that works.

For benefits of community, this was due to mcafee software. Mcafee is such a shitty product. Their product can't be uninstalled by Windows standard uninstall procedure and therefore they created utility called MCPR. Such a BS.
