nix no longer tells me why I can't build remotely #1572
Description
Derivation in question is a fetchgit derivation. In nix 1.11, when a remote builder refused to build a derivation, or nix didn't bother asking the remote builder, there would be a debug message along the lines of hook reply is "decline". No such message is printed anymore, making it a lot harder to figure out what's going wrong:
