https://tenant.auth0.com/asdf and https://custom-domain/asdf giving 404 error found. I couldn’t able to find the place to customise the behaviour. Configured tenant level error page (redirect) only working when there is any error in /authorize url, but not on this 404 path not found.

Hello Srikanth, Unfortunately, we do not currently support the customization of that 404 page. I suggest submitting the feature request via the link below: https://auth0.com/feedback Thanks, Art
