I'm also coming up against this with my aarch64 machines. The guix
version is the same on both of them, both machines are running
guix-publish with guix-0.14.0-6.0dcf675.
efraim@odroidc2:~$ guix --version
guix (GNU Guix) 0.14.0.1000-3b1ad

I checked the logs for guix-publish but all I have are entries like:
Jan 20 21:16:09 firefly guix[406]: GET /nar/gzip/h4s5s9zlbph0r27x4plfmh89r67s4mdq-dosfstools-4.1
