mix can't resolve any URLs #6057
Description
I am using Elixir 1.4.2 and Erlang 19.3 and when trying to install hex I get:
mix local.hex --force
** (Mix) httpc request failed with: {:failed_connect, [{:to_address, {'repo.hex.pm', 443}}, {:inet, [:inet], :nxdomain}]}
Could not install Hex because Mix could not download metadata at https://repo.hex.pm/installs/hex-1.x.csv.
Or while trying to do deps.get
mix deps.get
Failed to fetch record for 'gettext' from registry (using cache)

I found issues #3956 and #5731 , but neither of those helped. When opening the URLs in my browser they do work.
OpenSSL is up to date and I tried mix local.hex HEX_UNSAFE_HTTPS=1 which produced the same results. I am totally new to Elixir so I don't know what else to try.
Through a vagrant box on the same machine everything works like it's supposed to.
