Goutte / Guzzle - > cURL错误35：错误：1408F10B：SSL例程：ssl3_get_record：使用代理时版本号错误

I'm trying to scrape a website using Goutte (https://github.com/FriendsOfPHP/Goutte) in Laravel. It works fine but returns an error when using a proxy

$client = new Client([
            'curl' => [ CURLOPT_SSLVERSION => 1 ],
          ]);
$proxy = 'http://50.239.245.110:80';
$client->setClient(new \GuzzleHttp\Client(['proxy' => $proxy]));
$crawler = $client->request('GET', 'https://symfony.com/doc/current/components/dom_crawler.html');

$test = $crawler->filter('h1')->extract(['_text']);
dd($test);

I added 'curl' => [ CURLOPT_SSLVERSION => 1 ] since it said that it the ssl version was correct but it still displays the same error.
