nix build with custom SSL certificates fails

[bsoudan]

I'm trying to use nix and a set of custom scripts to manage user environments behind a proxy. When I try to build a derivation using nix-env or nix-instantiate/nix-store, I get:

download-from-binary-cache.pl: could not download ‘https://cache.nixos.org/j4vjmhby0v62l71l3ybzq5s49g043946.narinfo’ (Curl error 60)

I'm still troubleshooting some, but wondering if anyone else has run into anything like this. I am behind a web proxy, and also using a custom set of SSL certificates that includes a self-signed certificate, so it could be related to that.

Need more investigation here. Closing for now.

Adding '--option verify-https-binary-caches false' fixed this issue for me.
