Okay, I'm not sure why but here are some suggestions:

Did you authorize substitutes for ci.guix.info?

Also, did you set up X.509 certificates for use by Guix?

Yes, I don't know off the top of my head how much space it needs but
since the source alone is several gigabytes I recommend 15 GB.

You need to set this variable in the context of the guix-daemon:
