Is the socket file name displayed above correct?  Or did you specify
something else in the <build-machine> record?

Is the ‘GUIX_DAEMON_SOCKET’ environment variable defined on that
machine?

How do you run guix-daemon on the head node?  The patches discussed here
haven’t made it into the ‘guix’ package yet AFAIK.

Thanks for reporting the issue!
