Your understanding is correct :). However, looking at the
cuirass-remote-server.log file, I found:
--8<---------------cut here---------------start------------->8---
2021-07-29T22:31:48 fetching
'/gnu/store/hrn9hj7v1img3il6afh3r036aczvwnyd-xnnpack-0.0-1.bbe8824.drv' from
http://141.80.167.185:5558
2021-07-29T22:31:48 Failed to add
/gnu/store/slm0x0j05vyl3vqbjhgc0nch6jca9fp3-xnnpack-0.0-1.bbe8824 to store.
--8<---------------cut here---------------end--------------->8---
There are quite a few other "Failed to add" traces in the log, and they
all seem to involve the machine behind the .185 IP address.
Fetching the substitute manually from Berlin works:
--8<---------------cut here---------------start------------->8---
wget
http://141.80.167.185:5558/nar/slm0x0j05vyl3vqbjhgc0nch6jca9fp3-xnnpack-0.0-1.bbe8824
--no-http-keep-alive
--8<---------------cut here---------------end--------------->8---
but using "ensure-path" fails this way:
--8<---------------cut here---------------start------------->8---
scheme@(guix-user)> (set-build-options* s "http://141.80.167.185:5558")
$1 = #t
scheme@(guix-user)> (ensure-path s
"/gnu/store/slm0x0j05vyl3vqbjhgc0nch6jca9fp3-xnnpack-0.0-1.bbe8824")

Do you see any reason why ensure-path would fail while wget works?
Thanks,
