DNS Doesn't resolve albany.k12.or.us

I’ve been using 1.1.1.1 for my DNS server for a long time, but recently (and sadly I don’t have the exact date) we haven’t been able to access any albany.k12.or.us websites. The name doesn’t resolve when I test it with nslookup. I changed my DNS to 8.8.8.8 and it resolved right away. Here are further data. Not sure how I resolve this.

nslookup
nslookup albany.k12.or.us
Server: one.one.one.one
Address: 1.1.1.1

*** No internal type for both IPv4 and IPv6 Addresses (A+AAAA) records available for albany.k12.or.us
