title: SoapClient stays loading until timeout
body: <p>I'm trying to get informations from a Web Service with SoapClient, but for some reason, when I execute the code, it stays loading until timeout, and doesn't show any error. I already tried to set <code>php.ini</code> with <code>extension=php_openssl.dll</code> and set <code>extension=php_soap.dll</code>, tried to execute the code in xampp, in a website hosting and the error persists. In a moment I thought it was a problem in the page, but the link works fine <code>https://ws.correios.com.br/calculador/CalcPrecoPrazo.asmx?WSDL</code>.</p>
  <p>Here is my function:</p>
  <pre><code>    $options = [
      'cache_wsdl'     =&gt; WSDL_CACHE_NONE,
      'trace'          =&gt; 1,
      'stream_context' =&gt; stream_context_create(
          [
              'ssl' =&gt; [
                  'verify_peer'       =&gt; false,
                  'verify_peer_name'  =&gt; false,
                  'allow_self_signed' =&gt; true
              ]
          ]
      )
  ];
  
      $client = new SoapClient('https://ws.correios.com.br/calculador/CalcPrecoPrazo.asmx?WSDL', $options);
      
      $parametros = array('nCdServico' =&gt; '04510', 'sCepOrigem' =&gt; '82220020', 'sCepDestino' =&gt; '08090284');
      
      $response = $client-&gt;CalcPrazo($parametros);
      
      var_dump($response);
  </code></pre>
