Failed to open stream: HTTP request failed! in \wamp\www\wordpress\wp-includes\class-http.php on line 929

Running index.php from command line & load balancer health checks
Since wordpress’s execution logic relies on parameters filled by the php-apache connector (mod_php) running a php command line is not guarantied to produce the same results or any at all, all depending on your local settings.

Using wp-cron in backpress – problems with wp_remote_post, fsockopen error
From quick look at source mechanics seem very similar, my first suggestion for WP would be to try and bump HTTP transport to curl (I do it with plugin in WP so no idea about specific code). curl seems to be considerably more robust for corner cases and it’s not WP’s first choice.
