Issue on name resolution

Hello, everyone.
I’m having trouble on accessing my university website with 1.1.1.1 DNS. Using Google Public DNS and the standard ISP DNS server there are no problems. I tried to purge cache from the Purge Cache tool but the issue persists.
Here are the website: feis.unesp.br or www.feis.unesp.br

And here are the tests I’ve performed:

Cloudflare connection test:

DNSviz test:
https://dnsviz.net/d/www.feis.unesp.br/dnssec/

Lookup tests with Cloudflare and Google DNS:

nslookup www.feis.unesp.br 1.1.1.1
Servidor: one.one.one.one
Address: 1.1.1.1

*** one.one.one.one não encontrou www.feis.unesp.br: Server failed

nslookup www.feis.unesp.br 8.8.8.8
Servidor: dns.google
Address: 8.8.8.8

Não é resposta autoritativa:
Nome: sgcdweb.unesp.br
Address: 200.145.6.99
Aliases: www.feis.unesp.br

Is there something that I can do to solve this?

Best regards,
Lucas.

I have the same issue for the past several hours, 1.1.1.1 not accessible (I’m in Israel), 1.0.0.1 is accessible.
Link to the automated test:

The automated test shows I’m connecting to the Frankfurt data center.
Please assist.
Thanks in advance,
Steve

Hi, sorry for the issues. The problem is unesp.br nameserver is noncompliant and doesn’t return a signature for the DNSKEY:

$ kdig @200.145.241.1 feis.unesp.br DNSKEY +dnssec +short
257 3 5 AwEAAcJULe94U9TKKESLvjRAHqYsukRyS9/AO3BE4ebVKhbeZXdcC2jGC42GuQsKYmDEiTaqNSLQMmi58pxFsULoWvmR48AjloeoWOPOxeCAGNjwW6MS2bstqury25a7QydXuXjgCv723geD7mvnVoHBa3JRHk3Q5uggWCC0ifSZ/iYmgF0GJJf0V1UgjE47vf4WaUaeMF16Th1UKKn1YI9Q1XhL+rn1nwLdJF1fViCdEf++1h7sTxx08cuBmaq/VE/x9dbjnda7I0skYgIj4DyFIq/hDsGKSLXl6r9IKJz/lXifgzRWsu2Ps4vr3PB9vrPUtwtnFVuSuR2xdbTxTA5mwRE=

If you have a contact to the operator they could probably update their DNS software. I can try add a workaround.
