IdentityServer External auth provider - auth-callback - Redirection - 400 Bad request

Question

I am following https://www.scottbrady91.com/Angular/SPA-Authentiction-using-OpenID-Connect-Angular-CLI-and-oidc-client and https://www.scottbrady91.com/Angular/Migrating-oidc-c

Answer 1

Perhaps you mixed something up in routes or redirect_url configuration?

Based on configuration of the client and server you posted, redirect_url should be:

http://localhost:4200/auth-callback`

Yet, in the screenshot path is /call-back, not /auth-callback.

I would check if configurations (client and server) and Angular router all have same path /auth-callback configured.
