Build output links on the CI build details page doesn't work and return a bad gateway error.

Hello everyone,

I've been trying to get the following github guix action[1] 
working on a small repository,
to save times on guix pull the action tries to download an up to 
date snapshot from
the CI server. Using the following link structure:

#+begin_src
https://ci.guix.gnu.org/search/latest/archive?query=spec:tarball+status:success+system:x86_64-linux+guix-binary.tar.xz
#+end_src

This link used is the one provided on the details page at 
https://ci.guix.gnu.org/build/1342826/details
in the build output section, when you follow the link you will get 
the following error:

#+begin_src
502 Bad Gateway
#+end_src

The nginx configuration seems to be wrong an not pointing to the 
right place.

As followup questions:

This might be a hacky way to retrieve a snapshot or install a 
nightly release?
Is there a more official link to download a snapshot of Guix or a 
more official way to do it.
