从IndentityServer 3请求令牌时，为什么会出现HttpError

Question

I have a standard IndentityServer 3 application that I use to generate tokens for my applications. I deployed multiple instances of this application to different servers and I can successfully request tokens from all of them. Recently I deployed another instance to a Windows Server 2012 and started getting a HttpError when requesting tokens

I use the following code to request a token

var tokenClient = new TokenClient(identityServerUrl,clientId,clientSecret);

var result = tokenClient.RequestClientCredentialsAsync("Test").Result;

Any ideas on what may be causing IdentityServer 3 to get a HttpError?

Answer 1

This problem was occurring because of an IIS configuration. Double click on your server in IIS Manager and double click on Authentication

.

Make sure that obly Anonymous Authentication is enabled.

Very Important: Apply the same settings for your IdentityServer site.
