What I would expect:
As I specified the --fallback option, I would expect guix to start
building from source, as the substitution failed.

There are actually two bugs withing a single one here. The first one is
that you could not connect to the berlin publish server in less than 5
seconds (the timeout duration).
I have already observed such problems on the build farm and reported it
here: https://issues.guix.gnu.org/48468. It has been mitigated by
implementing keep-alive support[1]. However, I suppose that the
underlying issue is that guix-publish is in some cases over-flood and
fails to accept new connections.

The second issue is that as you noticed, the fallback option doesn't
have any effect.
Thanks,
Mathieu

FWIW, the network connection was very flaky then.
Taking more than 5 seconds to connect seems plausible here.
Greetings,
Maxime.
