Pihole - Change IP when site is blocked

Hi All

I am using Pihole Docker. Its running and working 100%.

When I visit a blocked site (Example reddit.com) it returns saying either it took to long to respond or not found (This is correct)

I want to change it to return a web page saying it is blocked. Either a Pihole page or I can create my own custom page that it will return where I can say "Blocked"

How would this be possible? Did Pihole not have a feature like this before?

We removed this intentionally, as it was only working for non-encrypted http sites. As the majority of sites today is https encrypted, the feature became senseless.
However, you could re-add it by setting the blocking mode to IP and add a page to display.

Some hints: Remove the advanced functionality of the 404 page (Blockpage) by PromoFaux · Pull Request #3910 · pi-hole/pi-hole · GitHub
