Error when run "composer update". Windows / Vagrant / Laravel Homestead

Installed stack: Windows 7 64x / Vagrant / Oracle VM Box / Laravel Homestead.

Mapping works, laravel's site's works. But when I run command: "composer update" - I get error message:

Failed to decode response: zlib_decode(): data error
