How to debug Pkg "failed to connect" issue?

[Arch Robison]

How do I go about debugging why the Julia package manager can't connect to Github?  I've tried the usual firewall workarounds (see below).  Either of the following works fine:

git clone https://github.com/JuliaLang/METADATA.jl

git clone git://github.com/JuliaLang/METADATA.jl

But within Julia, Pkg.init() fails with:

julia> Pkg.init()

INFO: Initializing package repository /nfs/fx/home/adrobiso/.julia/v0.5

INFO: Cloning METADATA from https://github.com/JuliaLang/METADATA.jl

ERROR: GitError(Code:ERROR, Class:OS, Failed to connect to github.com: Connection timed out)

I've already have the following variables set: 

HTTP_PROXY=http://proxy-us.intel.com:911

HTTPS_PROXY=http://proxy-us.intel.com:911

http_proxy=http://proxy-us.intel.com:911

https_proxy=http://proxy-us.intel.com:911

and I've run:

git config --global url."https://".insteadOf git://

git config --global http.proxy $HTTP_PROXY

Suggestions?

Given the error and that you want to use proxy. Maybe
https://github.com/JuliaLang/julia/issues/13472 ?

Thanks.  The advice in https://github.com/JuliaLang/julia/issues/13472#issuecomment-179454292 worked for me, except that since I was on Ubuntu, I used the following command instead of the yum step:

sudo apt-get install libcurl4-openssl-dev
