I don't know what the issue is. I am sorry, do not know how can I help. I tried this command: for NS in $(dig +short ns wisselkoersenvoorjeadministratie.nl); do dig +dnssec +short download.wisselkoersenvoorjeadministratie.nl @$NS; done 185.87.187.229 A 8 2 3600 20200507000000 20200416000000 27409 wisselkoersenvoorjeadministratie.nl.

I could not find anything similar to dnsviz.net in responses. Would it be possible just some geolocation nodes are broken and others work? delv works fine on that name to me. I do not have IPv6 connectivity, if that changes anything. I have never seen such diagram for a name on dnsviz. I think there is definitely something wrong with their server, maybe not only wrong signatures. It should be in your named-pkcs11 logs when rndc trace was increased to 5 at least. Checking what their servers responded would be most important. It seems I see different result than dnsviz.net. Checking from different regions might help, is possible. > > On Wed, Apr 29, 2020 at 11:52 AM Petr Menšík via FreeIPA-users < > freeipa-users@lists.fedorahosted.org> wrote: > >> Hi Tiemen, >> >> it might help you to use dig and delv to debug dns related issues. >> SERVFAIL is quite often some issue in DNSSEC validation.
