I think the redirect URL for Discord OAuth hasn’t been added in the (https://discord.com/developers/applications). Could you please check and ensure that the exact redirect URI being used by the app is registered there? Discord requires an exact match for redirect URIs, otherwise it will return an Invalid redirect error. @jasonhedman
