Composer connection

I'm trying to make laravel project with composer with bellow cmd cod:

composer create-project laravel/laravel laravel-santcum-api

but I get error like this:

[Composer\Downloader\TransportException]
  curl error 7 while downloading https://repo.packagist.org/p2/laravel/laravel.json: Failed to connect to 127.0.0.1 p
