What kind of sites, if you don't mind sharing?

I've been using pi-hole for 4 years now and I can remember two situations when I had to disable it - and one of those was cloudflare's fault (PS4 cloud saves don't work with 1.1.1.1 DNS)

If you download minecraft mods they are often hosted behind some forced ad-showing website (ad-fly or something). That can be a problem with pi-hole.

I needed to do this recently for eflorist.co.uk. I was unable to complete checkout without disabling pihole.
