pfBlockerNG-devel block pages

Networking & Firewalls
1

Hi all,
I’m using pfsense 2.4.5-RELEASE-p1 on my work environment and I just set up pfBlockerNG-devel to block some stuff.
I’m trying to understand when I get the following.
e.g. pic1
e.g. pic2

1908×1516 187 KB

And some other times I get the 1x1 pixel page.

Is it possible to get all the times the second one (black screen with the details) ?
I use blocking with geoIP, dnsbl groups, dnsbl categories and dnsbl safe search
Thanks in advance!

When the link it http you get the pixel, when it is https you get the certificate message because the certificate does not match.
