tauth fails to load example zones when running the compilation example

[balaziks]

I followed the “Compiling and running tdns” example and the end of README.md and after successfully compiling I tried to run ./tauth [::1]:5300 which resulted in

Hello and welcome to tdns, the teaching authoritative nameserver
Loading & retrieving zone data
Attempting to retrieve zone . from [2001:7fd::1]:53

Got error Notauth from auth 52.48.64.3:53 when attempting to retrieve powerdns.org.

So obviously the next command dig -t any time.powerdns.org @::1 -p 5300 +short didn't end up with expected output.

Maybe some policies on 52.48.64.3 changed so it won't provide the zone requested by tauth with AXFR query?
