Github connection timeout

git config --global http.proxy http://:@:
git config --global url.https://github.com/.insteadOf git://github.com/

I had the same problem and found solution. There is a rockspec that contains URL for nvim-client -git://github.com/neovim/lua-client. If you're behind some sort of firewall or proxy you're probably forbidden to use git protocol. If you try to issue

git clone git://github.com/neovim/lua-client

you will get that timeout error message. If you try same URL but use https protocol like this

git clone https://github.com/neovim/neovim.git

and succeeds then you need to configure 2 things:

1. Configure proxy for git.
2. Configure rewriting git:// urls to https:// urls

For simple proxies you can just configure it with git config http.proxy. If you have some exotic setupgitProxy scripts could help you - see examples here.

Now that you can connect via proxy you need to pass through proxy by using https instead of gitprotocol. There is an config option insteadOf for this:

git config --global url.https://github.com/.insteadOf git://github.com/

This will substitute git:// urls for https:// urls for all github repos.

After that I had successfully built neovim (make distclean and make).

Here are these options for .gitconfig:

[http]
    proxy =  http://:@:
[url "https://github.com/"]
    insteadOf = git://github.com/
