Emacs keeps throwing "Internal Server Error" behind proxy

Question

I spent a day debugging it but can't see what's wrong in my setup. I'm using Linux (Fedora 22) running Emacs 24.5.1, behind company proxy and have environment variables "http_proxy", "https_proxy", "ftp_proxy" all setup correctly. I also have "setq url-proxy-services ..." in my init.el.

I added MELPA as a repository using: (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/"))

But emacs keeps throwing this stack trace on error (emacs --debug-init):

Debugger entered--Lisp error: (file-error "https://melpa.org/packages/async-20150909.2257.tar" "Internal server error")

Here's my init.el for reference:

(require 'package)

(add-to-list 'package-archives
         '("melpa" . "https://melpa.org/packages/"))
(package-initialize)

(setq url-using-proxy t)
(setq url-proxy-services
       '(("no_proxy" . "^\\(localhost\\|10.*\\)")
         ("http" . "www-proxy.us.mycompany.com:80")
         ("https" . "www-proxy.us.mycompany.com:80")
         ("ftp" . "www-proxy.us.mycompany.com:80")))

Eventually I gave up on setting up proxy in emacs. Instead I now use cask which is an external python program which, among other things, downloads and manages emacs plugins. With cask I can now just set proxy environment variables and it all works perfectly. In fact cask method is better than setting in init.el since I frequently move between proxy and non-proxy environments. — ngupta
Can you please explain how you used Cask? I am having the exact same issue and gave up trying with proxies and emacs. But don't know how to use cask now. — SFbay007
@SFbay007 I also nearly gave up on emacs due to this proxy issue but cask saved it. With Cask I list all plugins I need in a ~/.emacs.d/Cask file and then I run 'cask install && cask upgrade' in ~/.emacs.d. Then installed plugins can be used from ~/.emacs.d/init.el. For example, you can find my emacs config on github. — ngupta

You can have a try with these variables

   (setq url-using-proxy t)
   (setq url-proxy-services
       '(("no_proxy" . "^\\(localhost\\|10.*\\)")
         ("http" . "proxy.address.company:port")
         ("https" . "proxy.address.company:port")
         ("ftp" . "proxy.address.company:port")))
