Twitch not refreshing the OAuth redirect uri?

[BarryCarlyon]

@Thial

That’s the strange part, nothing was changed.

I also have a WPF app which is displaying a prompt to log in via twitch and nothing other than changing /auth to /authcli in it was ever changed and there the prompt is also wrong while it was working fine before.

Nothing was changed, except for the changing the redirect URI?

You seem to have contradicted yourself?!

Recheck all your settings, resave all your settings, give it 10/30 minutes

And go from there.
