Keycloak login page displays "invalid parameter: redirect_uri"

Question

I use Keycloak authentication to authenticate the angular application, and so far I have been able to redirect my login to the Keycloak server. But when redirecting instead of the login page, I get a 500 error page with a messageInvalid parameter: redirect_uri

Answer 1

When you created the client in Keycloak, you set the required field "Valid Redirect URIs". Most likely, the template that you entered there does not correspond to the redirected uri that you send from your client. If you use port numbers, they must match too!
