Upgrading on 4.3 - Could not Establish Secure Connection to Wordpress.org

[atomicjack]

Just set-up the beta version, and clicked Update to the nightly build, but it keeps saying it cannot establish a secure connection to Wordpress.org even though, non-4.3 sites update fine.

Can you duplicate this reliably?

This warning is usually (almost always) caused by a HTTP timeout, which can happen easily if it's setup locally.

I have no other means of testing it in any other environment at the moment, however, multiple other WordPress installations are also run locally, and they all update perfectly. It's just this RC doesn't want too.

I just ran the update for a 5th time - and it was successful, no errors.

It seems it could be an issue with wordpress.org or something, as nothing changed on my local set-up.

Sounds like a network timeout then, the timeout on that request is probably the default 3 seconds, it can probably be increased..

Is this correct section of code?

if ( $c <= 50 || ( $c > 50 && mt_rand( 0, (int)( $c / 50 ) ) == 1 ) ) {
			require_once( ABSPATH . WPINC . '/http.php' );
			$response = wp_remote_get( admin_url( 'upgrade.php?step=1' ), array( 'timeout' => 120, 'httpversion' => '1.1' ) );
			/** This action is documented in wp-admin/network/upgrade.php */
			do_action( 'after_mu_upgrade', $response );
			unset($response);
		}
		unset($c);
	}
}

Seems to happen even when not updating.

It appeared at the top of the Updates page, whilst having the force-check set to 1 on the URL attributes.
