The similar command:

  guix machine --commit=5fa4814b4f12b82a7a7747bfacfb45b0348eae1e \
       -- time-machine --commit=1155a88308df7649fe74bd5bb8279a4d103ce386 \ 
       -- help

works for me.

It looks like a transient network issue.  I agree it is annoying.
First, it should automatically fallback.  And in any case, it should not
raise this ugly backtrace.
