composer: Composer\Downloader\TransportException - file could not be downloaded: Unable to locate peer certificate CN

Hi,

I am using composer with the WordPress BedRock project, and there’s a file that cannot be downloaded.

The error message is :

[Composer\Downloader\TransportException]                                                                                                                                   
  The "https://wpml.org//?download=1234&user_id=12345&subscription_key=my_sub_key" file could not be downloaded: Unable to locate peer certificate CN  
  Failed to enable crypto                                                                                                                                                    
  failed to open stream: operation failed  

This is a download for the WPML plugin, which allows composer. Here is my repo definition :

    {
      "type": "package",
      "package": {
        "name": "wpml-multilingual-cms",
        "type": "wordpress-plugin",
        "version": "3.3.6",
        "dist": {
          "type": "zip",
          "url": "https://wpml.org//?download=1234&user_id=123456&subscription_key=my_sub_key"
        },
          "require" : {
          "composer/installers": "~1.0"
        }
      }
    },

What do you think? Can you help me?
