Just moved my web app up to a staging environment and I'm getting this error. I suspect it has something to do with an IIS error I was getting locally on my machine and used the following code to resolve it.
It seems that this is not working on our staging environment. Not sure how to resolve at this point. Maybe someone can offer some suggestions.

[AuthenticationException: The remote certificate is invalid according to the validation procedure.]
   System.Net.Security.SslState.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, Exception exception) +1425171

[WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.]
   System.Net.WebClient.UploadDataInternal(Uri address, String method, Byte[] data, WebRequest& request) +302
   System.Net.WebClient.UploadString(Uri address, String method, String data) +170
   System.Net.WebClient.UploadString(String address, String method, String data) +35
   Telerik.Web.UI.SchedulerWebServiceClient.GetResources() +460

[Exception: Unable to retrieve response message]
   Telerik.Web.UI.SchedulerWebServiceClient.GetResources() +622

Setup web service in rad scheduler:

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

Handle on resource populating

    
            OnResourcesPopulating="RadScheduler1_ResourcesPopulating"  
        
                    protected void RadScheduler1_ResourcesPopulating(object sender, Telerik.Web.UI.ResourcesPopulatingEventArgs e)  
        
                    {  
        
                        HttpCookie cookie = FormsAuthentication.GetAuthCookie(User.Identity.Name, false);  
        
                        string cookieHeader = string.Format("{0}={1}", cookie.Name, cookie.Value);  
        
                        e.Headers.Add(HttpRequestHeader.Cookie, cookieHeader);  
        
                    }

Hello,

Since you're accessing the RadScheduler web service via HTTPS, you'll need to handle the certificate validation using the ServerCertificateValidationCallback.

This is a short sample. Be sure to actually verify the certificate in the actual production code.

ServicePointManager.ServerCertificateValidationCallback = ValidateCertificate;

// ...

protected virtual bool ValidateCertificate(Object obj, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)

{

if (errors == SslPolicyErrors.None)

return true;

return false;

}

I hope this helps.
