Failing to login using Facebook

[kudakwashegore]

I set up my MVC site to use Facebook and Google Auth. Google is working well, but I am always getting the following error when trying to use Facebook.

Message: Failed to retrieve an Access Token from Facebook.

StackTrace: 
at SimpleAuthentication.Core.Providers.BaseOAuth20Provider`1.RetrieveAccessToken(String authorizationCode, Uri redirectUri)
at SimpleAuthentication.Core.Providers.BaseOAuth20Provider`1.AuthenticateClient(NameValueCollection queryStringParameters, String state, Uri callbackUri)
at SimpleAuthentication.Mvc.SimpleAuthenticationController.AuthenticateCallback(AuthenticateCallBackInputModel inputModel)

Hi @kudakwashegore

what nuget package version of SimpleAuth are you using?
also, what mvc version?
does your code redirect to the facebook site OK? you get asked to log in ok (with FB?) etc?

Hi @PureKrome

I am using SimpleAuthentication.Mvc v0.6.0.0. on System.Web.MVC 4.0.0.0
The code redirects to Facebook and login without any problem. Then when Facebook redirects back to {domain_name_here}/authentication/authenticatecallback?providerkey=facebook&code={some long code here}

That's when the error is displayed.

I got it working by deleting SimpleAuthentication.Core installed via NuGet package manager & replacing it with SimpleAuthentication.Core.dll from GitHub source code. I noticed the GitHub version is more recent than the NuGet version
