I am using two piholes (one as backup mostly) on my home local network.
It works beautifully. They both use my opnsense router to use DNS, which goes
out my vpn client. I check that dnssec is supported, and the test on the website
says that it is. If I then click the button to use enable dnssec, it changes the
dns server by adding #53 to the end of the ip address. This is now permanent can
can not be undone. If I try to edit and save it, pihole changes it back. If I disable
dnssec, and then change the dns ip, pihole changes it back. If i ssh into that pihole,
it can no ping any address (like google). Therefore, it cannot update, it cannot be
repaired, etc. Pihole also just makes endless calls to try and get the right time, but
cannot reach the NIST servers. It is now useless. The only way to fix it, is to
reinstall the whole thing. If you make the mistake of enabling dnssec again, it
is broken and you have to start all over.
That none of this happens
What I described above
Since it can no longer reach anything, I cannot upload the logs
