Raspbian.raspberrypi.org failing DNSSEC

The issue I am facing:
The url raspbian.raspberrypi.org is showing as "BOGUS" which I gather is a failure of DNSSEC. I've noticed a few other URLs do the same over the last few weeks but have not payed attention to them. Turning of the DNSSEC option in pihole of course resolves this. Running the DNSSEC link on the DNS configuration tab of PIHOLE is successful. Using DNSSEC Analyzer - raspbian.raspberrypi.org it "seems" like the results are fine. Direct NSLookup to router is successful, but I'm assuming it doesnt use DNSSEC.

Details about my system:

2 PI Holes in a failover cluster (VIP) point to the router (Ubiquiti Unifi Dream Machine Pro) that in turn points to 8.8.8.8 and 8.8.4.4. Cable modem is in bridge mode.

What I have changed since installing Pi-hole:
No recent changes to PiHOLE, updates are frequent on the router.

Minor correction - this is a domain, not a URL.

BOGUS means "I've found a signed record and the signature is bad."

Check that the time on the Pi is correct for your local time zone, and you can also try a different upstream DNS server to see if the response from a different server is the same.

Here is what I get in a query for this domain with unbound as a local DNS resolver:

This domain was always problematic with Pi-hole/dnsmaq. I moved DNSSEC to a Unbound server to be sure it works.

The cause could be that the two authorative servers have different serial numbers for that domain.

I'm not following you here. This is the complete log from an online instance of unbound dig for this domain. Where would different nameservers be involved?
