nanobsd build fail on RELENG_12 and 13

I all of a sudden started getting an odd build failure on RELENG_12 and
RELENG_13 nanobsd scripts, for amd64 and i386. The error comes up as a
DNS issue, but DNS looks to be fine on both VMs

ie

root@nano13-amd64:/tmp # fetch -o /dev/null
http://pkg.FreeBSD.org/FreeBSD:13:amd64/latest/Latest/pkg.txz
/dev/null                                             8545 kB 4040
kBps    03s
root@nano13-amd64:/tmp #

but the script errors out with

pkg: Error fetching
http://pkg.FreeBSD.org/FreeBSD:12:amd64/latest/Latest/pkg.txz: No
address record

and same on the other RELENG_13 VM

+ env 'BATCH=YES' 'ASSUME_ALWAYS_YES=YES' 'PKG_DBDIR=/var/db/pkg'
'SIGNATURE_TYPE=none' /usr/sbin/pkg add /_.p/pkg-1.17.1.pkg
pkg: Error fetching
http://pkg.FreeBSD.org/FreeBSD:13:amd64/latest/Latest/pkg.txz: No
address record
Address resolution failed for
http://pkg.FreeBSD.org/FreeBSD:13:amd64/latest.
Consider changing PACKAGESITE.
Bootstrapping pkg from
pkg+http://pkg.FreeBSD.org/FreeBSD:13:amd64/latest, please wait...
+ umount /usr/obj/nanobsd.alix2apu/_.w/dev


The nightly build scripts are just

#!/bin/sh
cd /usr/src
/usr/local/bin/git pull --ff-only
cd /usr/local/nanobsd
sh ./nanobsd.sh -c alix-apu64.conf

Could it be related to
https://cgit.freebsd.org/src/commit/?h=stable/12&id=6cd271fbc243b9b2c6e657cd7772e3bafa210be0
?

Going to try and reset to before that and rebuild
