[FIXED] Getting error while installing laravel installer in window 10

Issue

I am using Windows 10 and composer is installed. When I try to install laravel installer globally using this command:

composer global require laravel/installer

[Composer\Downloader\TransportException]
The "https://repo.packagist.org/packages.json" file could not be downloaded: 
failed to open stream: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

It means package not downloaded. I am not using any proxy server. Composer diagnose result is listed below:
