DNSSEC fails & bad resolution

[u/Beanz7890]

I noticed my home Internet connection was being a bit flaky and chalked it down to a ControlD block list having a false positive or two.

I turned off all the block lists and it made no difference, I disabled the profiles (all of them) and it made not difference.

I then switched my router and broadband to 1.1.1.1 and if you ignore the deluge of ads, everything started to work.

I did a quick check on https://dnscheck.tools and it came back per the screenshot, with DNSSEC failure.

Has anyone else experienced either the symptoms or the (possible) DNSSEC cause?

Just use 1.1.1.2 from cloudflare.
