The remote certificate is invalid according to the validation procedure. external login with twitter

Question

It's an asp.net mvc5 application. Still under development. I am using 'twitter' login. When I click on 'login with twitter', it just throws an error on the screen. This is pretty weird because everything was working good and all of a sudden I see this error.

The only thing changed is when i started my computer, it said system date changed and asked me to press 'f1' and change the date. I did it. I am not sure if that has something to do with the error.

The error is attached. Would be great if someone can show some light

Default code snippet.

Just Replace the above code snippet with the one given below in Startup.Auth.cs class and replace your own Consumer Key and Consumer Secret.

app.UseTwitterAuthentication(new TwitterAuthenticationOptions
        {
            ConsumerKey = "XXXXXXXXXXXXXXXXXXXXXX",
            ConsumerSecret = " XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX ",
            BackchannelCertificateValidator = new Microsoft.Owin.Security.CertificateSubjectKeyIdentifierValidator(new[]
            {
