If I change the code and port to this:
/* Configuration variables for the JSON-RPC server */
$rpc_host = 'rpc.blockchain.info';
$rpc_port = '443';
$rpc_user = 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX';
$rpc_pass = 'PASSWORD';
require_once('jsonRPCClient.php');
$bc = new jsonRPCClient('https://' . $rpc_user . ':' . $rpc_pass . '@' . $rpc_host . ':' . $rpc_port);
$balance = $bc->getbalance();
?>
It will not connect??
