tunneling socket could not be established, statusCode=400

[everton3x]

Hey!

I installed Atom from the * .deb (64bits) file available on atom.io, in Linux Mint 18.1 KDE.

When I try to install a package, the following message returns:

Tunneling` socket could not be established, statusCode = 400

The connection to the internet is under a corporate proxy. The entire system works well with the global proxy configuration made in Linux Mint configurations, except Atom and apm.

For example, the apm install tool-bar or apm search tool-bar commands return the same error

tunneling socket could not be established, statusCode = 400.

When opening the package installer within Atom, the same error appears.

Apm --version:
Apm 1.16.1
Npm 3.10.5
Node 6.9.5 x64
Python 2.7.12
Git 2.7.4

I have looked for apm config set proxy http://<IP>:<port>, apm config set http-proxy://<IP>:<port> and apm config set https-proxy http://< IP>:<port> and others similar and the error continues to occur.

I have the same problem some months ahead.

$ apm --version apm 1.19.0 npm 3.10.10 node 6.9.5 x64 atom 1.25.0 python 2.7.14+ git 2.16.3
