远程服务器返回错误：（400）错误的请求Microsoft.AspNet.Membership.OpenAuth

我使用Microsoft.AspNet.Membership.OpenAuth创建新的asp.net webform .net 4.0并配置AuthConfig。 CS：远程服务器返回错误：（400）错误的请求Microsoft.AspNet.Membership.OpenAuth

OpenAuth.AuthenticationClients.AddFacebook(
       appId: "my appId", 
       appSecret: "my appSecret");

在Facebook的应用程序配置：网站与Facebook登录：http://www.tindep.com

但是，当我用Facebook登录它的错误：

虽然Google，Twitter，msdn登录成功（查看tindep.com/Account/Login.aspx）这只是在托管（tindep.com/Account/Login.aspx）时出错。 localhost：57846/Account/Login.aspx登录Facebook成功。

请帮助我找到原因。

非常感谢！
