Hi George,
I have been reading this page:
https://support.cloudflare.com/hc/en-us/articles/360021111972-Troubleshooting-DNSSEC
Taking this error from the log file using Unbound V1.9.4:
03/10/2019 15:29:45 C:\Program Files\Unbound\unbound.exe[11788:0] info: validation failure <5a196f4c-afe8-442e-b258-ee7373f136a5.is-cf.cloudflareresolve.com. A IN>: DS got unsigned CNAME answer from 2606:4700:4700::1001 and 1.0.0.1 for DS is-cf.cloudflareresolve.com. while building chain of trust
================================
There is no 'ad' flag present in the response so DNSSEC has failed using unbound and it returns no data hence the error message in the log file.

Using my ISP's router I get this returned with an NSEC record to say the name queried does not exist (have I got that correct?)

================================
The NSEC I think says remove the first subdomain (if doing a DNSSEC chain of trust walk) and try again. Repeat as many times as required.
So, if I knock off the first part of the subdomain: 5a196f4c-afe8-442e-b258-ee7373f136a5 I get the same results
If I then knock off the: is-cf I see this result:

Which does have the 'ad' flag set and unbound returns the data. The same is true for the ISP's router.
So in this instance the domain name validates and therefore all is OK.
Using:
http://dnsviz.net/d/5a196f4c-afe8-442e-b258-ee7373f136a5.is-cf.cloudflareresolve.com/dnssec/
DNSSEC is validated and all looks just fine.
The same is true for:
https://dnssec-analyzer.verisignlabs.com/5a196f4c-afe8-442e-b258-ee7373f136a5.is-cf.cloudflareresolve.com
These words I think explain what is happening:
"Dig also retrieves the public key used to verify the DNS record. A domain's DNS records are all signed with the same public key. Therefore, query for the root domain's public key, not the subdomain's public key:"
They are on this page (mentioned at the start):
https://support.cloudflare.com/hc/en-us/articles/360021111972-Troubleshooting-DNSSEC
So unless my reading and understanding of what should be happening is totally incorrect Unbound should be ignoring subdomains and tracking back to the actual domain name and if that validates then it should return the appropriate data.
If I have this wrong then dnsviz and verisign should also fail the DNSSEC checks but they don’t appear to do so.
Please let me know if I still have this all wrong and apologies if I have.
Regards
Ray

Hi George,
Thanks for that (I hope)
Having added that line into the configuration I see a different result. See the two attached images
Not Active: # module-config: "iterator" - DNSSEC enabled
Active : module-config: "iterator" - DNSSEC disabled
In the config file.
So if I leave DNSSEC enabled, whilst the test a https://1.1.1.1/help shows DOT is not enabled it is in fact all working OK as expected, is that correct?
I just wanted to make sure I was understanding what is happening.
So all in all I think I have it all working...
Just as an aside Firefox (if you use that) does DOH directly to the cloudflare servers and that also works OK.
Some other test servers that may be useful:
https://rootcanary.org/test.html
https://en.internet.nl/
https://www.dnsleaktest.com/

Hi Ray,
It seems that cloudflare is using special subdomains (answered only from their 1.1.1.1 resolvers) for the online checks and they are not handling DNSSEC properly in regards to answers for these special subdomains.
Unbound is complaining about not being able to build a trust chain because it can't get the DS information.
I suspect that if you turn off DNSSEC validation on your unbound
module-config: "iterator"
the online check should work. Although I would advise to turn it on again after you do the online check.
And just to be clear, this does not mean that 1.1.1.1 cannot do DNSSEC.
I am only talking about the subdomains used for this specific online check.
