RadAsyncUpload SSL Select Button Doesn't work

[Head]

I am using RadAsyncUpload in a form which work fine under HTTP. As soon as I turn SSL on and access page through HTTPS, when I click select button

•  it doesn't work (open dialog to choose file) on IE 7 and 9, but works fine on firefox.
• on firefox dialog open and after selecing a file it start uploading file then in give red light with error in firebug (uncaught exception: Error while uploading, HTTP Error code is: 0)
• if on IE I disabled silverlight Add-on,I can open popup to choose a file, but progress bar keep loading and never complete uploading file or gives error

 
I have tried all below but still same issue

1.  Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function() { return false; };, 
2. setting EnableFileInputSkinning = false
3. checking .axd is correctly configured in webconfig.

Also, if i set DisablePlugins="true", the dialog appears but file fails to load correctly and give red light.

Hello,

I have tested a sample project under https and everything is working correct (with all upload modules). Could you test our online demos under https? Did you encountered some issues? Please setup a sample project that reproduces the issue and send it for a local test.
