I believe this is fixed by this commit: http://git.savannah.gnu.org/cgit/guix.git/commit/?id=d213cc8c7f085428e3c64243b0d163423e4bb5f6 The crux of the problem was that we were sending too many requests at once, and for some reason the server would close the connection prematurely (in HTTPS, not HTTP). It didn’t make sense to send too many connections at once anyway, because the server won’t accept that many (see ‘keepalive_requests’ in nginx), so the commit above sets a maximum. The problem could be reproduced with: --8<---------------cut here---------------start------------->8--- (use-modules (guix scripts substitute) (guix build utils) (web request) (web uri) (srfi srfi-1) (gnutls)) (define base-url (or (getenv "URL") "https://mirror.hydra.gnu.org";)) (define base-uri (string->uri base-url)) (define index.html (build-request (string->uri (string-append base-url "/nix-cache-info" ;; "/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee.narinfo" ;; "/yihvhxv3xyyvl1m2cy1lnf1lyi9h76fk.narinfo" )))) (define http-multiple-get (@@ (guix scripts substitute) http-multiple-get)) ;; (set-log-level! 5) ;; (set-log-procedure!
