Expected behaviour:

Block page showing on HTTP & HTTPS requests.

Actual behaviour:

Block page only shows on HTTP, not HTTPS requests

Steps to reproduce:

1) Make sure the device you are using is routed through a Pi Hole DNS.

2) Go to a blocked site, whether it be blacklisted manually or from a list (for this example, we are using t.co)

3) Go to the site using HTTP, you should get a page like this (CSS or something seems broken, but that's not what we are focusing on right now.)

4) Now try going to the site using HTTPS. Instead of a block page, you are just given a connection error. Now this is an issue considering most sites use HTTPS and this simply gives a false understanding to the user.

This is as intended, you can not intercept HTTPS/TLS traffic without presenting a TLS certificate in the name of the site. This is not operationally feasible and would be considered a breach of security as a man-in-the-middle attack.
