[CLOSED] Getting "Request Failure Status code: Status Text: communication failure in latest version 4.5.1

[MOHAMMEDRAFI]

Hi,
I am getting error while loading data through ajax call into grid. For processing of data from database it will take approx. 1 min 30 sec. in that case i am getting error message: Request Failure Status code: Status Text: communication failure. (I am not able to close that box also).
Below is my code:

 Html.X().GridPanel()
.ID("GridOrderDashboard")
.Layout(Ext.Net.LayoutType.Fit)
.Padding(0)
.Border(true)
.AutoScroll(true)
.Scroll(Ext.Net.ScrollMode.Both)
.Height(320)
.AllowDeselect(false)
.Store(storeitem =>
{
    storeitem.Add(
    Html.X().Store()
    .ID("GridOrderDashboardStore")
    .PageSize(5)
    .AutoLoad(true)
    .RemoteSort(false)
    .RemotePaging(false)
    .Listeners(listen => { listen.Load.Fn = "onGridLoad"; })
    .BuildProxy("~/AjaxData/GetOrder/")
    .Model(model => model.Add(Html.X().Model()
    .IDProperty("JOID")
    .Fields(fields =>
    {
        fields.Add(Html.X().ModelField().Name("dataid"));
        fields.Add(Html.X().ModelField().Name("status"));
       
    })
    ))

As per forum i have added below tag in Web.config but still i am getting above error message.
In Web.config file

ajaxTimeout="180000"

in Controller side:

  [Ext.Net.DirectMethod(Timeout=90000)]

but still getting error.
