发送失败:连接被重置

我的代码:

$curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, 'http://site/index.php?1c.upload&filename=' . $filename);
    curl_setopt($curl, CURLOPT_COOKIE, $cookie);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $files); //Array CURLFile
    echo $out = curl_exec($curl);

当我尝试发送10Mb的文件时-都正确。当我尝试发送文件~200Mb -我得到错误

55, Send failure: Connection was reset

或

56, Recv failure: Connection was reset

我试着写curl_setopt($curl, CURLOPT_HTTPHEADER, ['Expect:']);不是结果……然后试试curl_setopt($curl, CURLOPT_TIMEOUT, 3600); -相同的…

:

max_execution_time = 3600
max_input_time = 3600
upload_max_filesize = 500M
post_max_size = 500M

同样尝试set_time_limit(3600);在php文件…
