ADFS 3.0 not redirecting on signout

Question

I have tried the following urls for logout:

https://adfs.example.com/adfs/ls/?wa=wsignout1.0&wreply=https://localhost:32971/ https://adfs.example.com/adfs/ls/?wa=wsignout1.0&wreply=http://localhost:32971/ https://adfs.example.com/adfs/ls/?wa=wsignoutcleanup1.0&wreply=https://localhost:32971/ https://adfs.example.com/adfs/ls/?wa=wsignoutcleanup1.0&wreply=http://localhost:32971/

This is coming from the site http://localhost:32971

On the ADFS side I have the WS-federation Passive Endpoint set as https://localhost:32971/

This is also set as the default, so what am I missing here?

            string absoluteUrl = HttpContext.Request.Url.AbsoluteUri;
            string replyUrl = absoluteUrl.Substring(0, absoluteUrl.LastIndexOf("/") + 1);
            var issuer = FederatedAuthentication.WSFederationAuthenticationModule.Issuer;
            var signOutUrl = WSFederationAuthenticationModule.GetFederationPassiveSignOutUrl(issuer, null, null);
            WSFederationAuthenticationModule.FederatedSignOut(new Uri(signOutUrl), new Uri(replyUrl));
            FederatedAuthentication.SessionAuthenticationModule.SignOut();
            Response.Redirect(Request.RawUrl);

Try this. Might help.
