I am using the Q1 2009 version of the ASP.NET AJAX RadControls and we have created a calendar that heavily uses the RadScheduler. The site works on the server when you visit it locally or remotely via the IP, but when we try to access it using the SSL address that runs through our hardware load balancer it will not work. We have a previous version of the same application that works and the main difference between the two is the use of the WebService to populate the data in the RadScheduler.

The error that we get when attempting to access the new website:

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond ###.###.###.170:443

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond ###.###.###.170:443

Similarly, we get a WebException in the event viewer that states:

Exception information:

    Exception message: Unable to connect to the remote server

Any help is greatly appreciated.

Hello Anthony,

When binding to a Web Service the scheduler will call it from the server to obtain a list of resources (from the GetResources method). This is only needed when using resource grouping otherwise the resources can be loaded from the client too. You can disable the server loading of resources by setting:

<telerik:RadScheduler runat="server" ...>

<WebServiceSettings Path="SchedulerWebService.asmx" ResourcePopulationMode="ClientSide" />

</telerik:RadScheduler>

If you are using resource grouping then please verify that the configured web service URL is accessible from the server that hosts the page.

Kind regards,
