ASP.NET 4.6 OpenID Connect 404 Problem

[damien113]

I am having a really hard time getting OpenIDConnect to work properly with this asp.net 4.6 mvc 5 project. Recently I was getting a 404 error and ended up adding a custom route to the callback action to get it to work past that. AFter that I started getting a error about GetExternalLoginInfoAsync() returning null and getting a nullreferenceexception. This is what my config looks like with some things redacted, along with the routing. Also the image provided is one of the errors I get,if i dont use custom routing i just get a 404 error. If anyone has a sample project connecting to WHMCS with OpenID Connect in C# with Owin, let me know.

OpenIdConnect nonce cookie is there, along with session ID, also in the URL it is sending the state and the code which is below.

    https://localhost:44348/signin-oidc/?code=e33dab0ae5e9640ef731c460180780092703727b&state=OpenIdConnect.AuthenticationProperties%3D-JlLC-VdZi-KZst8OY4JikRrl59vm19HATAcOaqUv8a22U8ch9gC_IJARHlsvaDKZQrqfeTewtdk5d-KcZSrUR3qCoJVcmzNRDP8C0JJ2NH9ql42J3H1xkxEzoAvJ0wxITy-tCj5H-N-bYhMZbO4kB8s2S4msCF0kEDzgipoPmGfZfreUeyYcerwK_OJGH3uYKUYa1NjqA0G-hlhiYpUj8DUp59EXpDz6sr1wtohTiI

 

 

 

Code

 var json = "";
            using (WebClient wc = new WebClient())
            {
                json = wc.DownloadString("http://orders.data443.com/oauth/openid-configuration.php");
            }

            var settings = new OpenIdConnectAuthenticationOptions
            {
                Authority = "https://orders.data443.com/oauth/",
                ClientId = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
                ClientSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
                RedirectUri = "https://localhost:44348/signin-oidc/",
                CallbackPath = new PathString("/signin-oidc/"),
                Configuration = new OpenIdConnectConfiguration(json),
                ResponseType = OpenIdConnectResponseType.Code,
                SignInAsAuthenticationType = "Cookies",
                TokenValidationParameters = new TokenValidationParameters
                {
                    ValidateIssuer = false,
                },
                Scope = "openid email profile"
            };
            app.UseOpenIdConnectAuthentication(settings);

Routing    

routes.MapRoute(
            name: "signin-oidc",
            url: "signin-oidc",
            defaults: new { controller = "Account", action = "ExternalLoginCallback" });
