OK.

Without more info, it’s hard to tell, but there are derivations that are
marked as “non-offloadable”, essentially because it’d take more time to
transfer them and build them remotely than to build them locally.  Among
those derivations are profiles (built by ‘guix package’) and many of the
small items built by ‘guix system’.  It could explain what you’re
seeing.

Something like ‘guix build libreoffice --no-substitutes’ should be
offloaded, provided --max-jobs is appropriate as discussed before.

HTH,
