I've seen this a few times, and it seems like guix pull remembers old
substitutes. I tried disabling one of the substitutes that guix-daemon
is configured to use since it wasn't online at the time, but it tries to
use it anyways:

guix pull --substitute-urls='http://10.0.0.15:8081 http://10.0.0.15:8082' --branch=elfutils-0.172 --url=/home/vagrant/src/guix-bare

This bug was due to the fact that the ‘compute-guix-derivation’ program
would open a new connection to the store, and thus it would not inherit
the build options of its parent ‘guix pull’ process (substitute URLs,
build hook, timeouts, etc.).

Should be fixed with 790c3e019a5410018bd31596c2dcda5d0efb0d36.

Thanks,
Ludo’.
