recaptcha error in .net - timeout

I am facing error with recaptha, timeout.

I have specify all keys and just valid() calpcha function on code behind. It waits for while and time out.

More over, When doin开发者_运维问答g page.Isvalid() with capcha, it is alway false, what should be the reason?

  <recaptcha:RecaptchaControl ID="recaptcha" Theme="white" runat="server" PublicKey="6LdwMMgSAAAAALdraGklD-N1Jfr5Fuxq6gyaJMy7"
                                            PrivateKey="6LdwMMgSAAAAAKV6hOjAHdFURCUZ6oS_NmxF8iaD" />



 recaptcha.Validate();

Just wanted to point this out: you should hide your actual private Recaptcha key. Don't want people seeing that!

try to run without configure your application in IIS, you will get solution
