You've changed the DNS at your domain registrar, but redirect.pizza isn't detecting it yet?
It may take up to 24 hours before DNS changes have propagated the internet.
You can do 3 things:
- Check the changes via a DNS propogation checker, to see if it's propagating correctly, for instance https://www.whatsmydns.net/#A/example.com
- Press the 'refresh' icon next to the required DNS change in redirect.pizza to force a DNS re-check.
- Done 1 & 2? Have patience, get some cookies, have some tea.
