Answer 1

In my case it was the proxy blocking the communication with Wordpress server.

I fixed it by following this guide. ^mirror

Basically I had to define these rules into wp-config.php:

/* Configure proxy Server */
define('WP_PROXY_HOST', 'x.x.x.x');
define('WP_PROXY_PORT', '8080');
define('WP_PROXY_USERNAME', '');
define('WP_PROXY_PASSWORD', '');
define('WP_PROXY_BYPASS_HOSTS', 'localhost');

Answer 2

Check "Plugins / Add New" page. If there is same error instead of featured plugins list, then it basically means that WebServer can't connect to the web. Try temporary disable firewall and see if problem is solved. And if it is - you need to add rules for outgoing traffic for your WebServer (httpd in Apache case).

Other option is check, if SSL module enabled in your WebServer (mod_ssl in Apache).
