Hi all, I’ve got a typical newbie problem. How can I use Julia behind a corporate proxy with authentication? I already set `http_proxy` in the env and git works due to `--global http.proxy` magic. I’ts a simple download that causes the failure:

How can I inform julia about the proxy situation? Most tools have problems with this proxy/authentication settings.
Any help is greatly apreciated!
Cheers, Jörg

Atom used to work behind a proxy. So i just used Juno as the IDE and it was fine

Thanks for the fast response. I installed Atom and it has the same problem. I set the proxy using apm as recommended, I see the proxy in the commandline. In Wireshark I see that the authentication headers are simply missing ☹ .

Does your corporate firewall block binary downloads from non-authorised sites? The only workaround I have is to download the packages when not connected to the corporate network. Pure source packages download fine, but many with a binary download are toast. I understand why this is set up like this, but it can be rather frustrating.

@jottka I have met a similar problem
Please look at [Initialize Julia v0.6.2 behind a proxy · Issue #25245 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/25245)
