PHP致命错误：未捕获的SoapFault异常：[HTTP]错误获取http标头

I'm trying to create a soap connection PHP 7.2 . My array include "HtmlBody" variable. That include 5000 characters. If I send about 2000 characters, it works on my apache server. But other hosting or other Apache server can send even more than 5000 characters in the same configurations . Can someone help me out?

    ini_set('default_socket_timeout', 5000);
    ini_set('soap.wsdl_cache_enabled',0);
    ini_set('soap.wsdl_cache_ttl',0);
    $baglan2 = new \SoapClient("https://api.-----.com/max/post.asmx?WSDL",
        array(
            'soap_version'=>SOAP_1_2,
            'exceptions'=>true,
            'keep_alive' => false,
            'connection_timeout' => 5000,
            'trace'=>1,
            'cache_wsdl'=>WSDL_CACHE_NONE,
            'compression'   => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | SOAP_COMPRESSION_DEFLATE,
            "stream_context" => stream_context_create(
                array(
                    'ssl' => array(
                        'verify_peer'       => false,
                        'verify_peer_name'  => false,
                    ),
                    'http'=> array(
                        'timeout' => 60,
                        'ignore_errors' => true,
                    )
                )
            )
        ) 
    );        
    $sonuc2 = $baglan2->PostHtml($veriler_PostHtml);
