This is with the latest Emacs Version 27.2 (9.0) for Mac OS X:

error in process sentinel: Error retrieving: https://elpa.gnu.org/packages/archive-contents (error connection-failed "connect" :host "elpa.gnu.org" :service 443) [2 times]

I can access that address in a web browser fine.

My .emacs file contains a basic package configuration:

(require 'package)

(add-to-list 'package-archives
             '("melpa-stable" . "https://stable.melpa.org/packages/") t)

(package-initialize)

I see others have this issue, but it's a very different issue, the answers suggest this was fixed in Emacs 27+, which I'm already using.

Error retrieving: https://elpa.gnu.org/packages/archive-contents (error http 400)

  • It may be a temporary network glitch. What happens if you wait a few minutes and try again?

  • I deleted ~/.emacs.d, did a full reinstall of the latest Emacs for Mac OS X, waited several hours, and I consistently get the exact same error. I can also reliably load that web address in a web browser. I have a very good Internet connection.

    @clay I have the same problem; it's not just you.

    Further to my previous comment, I've downgraded from Emacs 27.2.2 to 27.1.1 and things are now working fine.

For me, a fix is:

(when (equal emacs-version "27.2")
  (setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3"))

I found this at Error retrieving: https://elpa.gnu.org/packages/archive-contents (error http 400)

EDIT:

The problem is only on some platforms, so I've changed that to:

(when (and (equal emacs-version "27.2")
           (eql system-type 'darwin))
  (setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3"))
