file_get_contents(): SSL operation failed with code 1 #aws #apache #xampp #ubuntu

hoy se me presento el siguiente error al implementar en mi vps el recaptcha de google, el error es el siguiente:

Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed in /web/configuracion/captcha.php on line 14 Warning: file_get_contents(): Failed to enable crypto in /web/configuracion/captcha.php on line 14 Warning: file_get_contents(https://www.google.com/recaptcha/api/siteverify?secret=dadkasklklsda23uisjksadkjl&response=&remoteip=55.55.55.55): failed to open stream: operation failed in /opt/lampp/htdocs/web/configuracion/validarCaptcha.php on line 14

codigo original:

$llave="dadkasklklsda23uisjksadkjl";
$ip=$_SERVER["REMOTE_ADDR"];
$captcha=$_POST['g-recaptcha-response'];
$verificarCaptcha=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=$llave&response=$captcha&remoteip=$ip");
$arregloCaptcha=json_decode($verificarCaptcha,TRUE);
if($arregloCaptcha["success"])
{
return true;
}

Solución:

$llave="dadkasklklsda23uisjksadkjl";
$ip=$_SERVER["REMOTE_ADDR"];
$captcha=$_POST['g-recaptcha-response'];
$ch =  curl_init("https://www.google.com/recaptcha/api/siteverify?secret=$llave&response=$captcha&remoteip=$ip");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$verificarCaptcha = curl_exec($ch);
$arregloCaptcha=json_decode($verificarCaptcha,TRUE);
if($arregloCaptcha["success"])
{
 
return true;
}
