Выдает ERR_CONNECTION_RESET. Как исправить?

Question

Есть файл подключения к серверу:
var socket = new WebSocket('wss://site.ru:8443/components/socket.php');
socket.onopen = function(event) { console.log('WebSocket is connected.'); };

При его запуске в консоли браузера такая ошибка:
WebSocket connection to 'wss://site.ru:8443/components/socket.php' failed: Error in connection establishment: net::ERR_CONNECTION_RESET

Bот сам сервер:
<?php
$host = 'site.ru';
$port = '8443';
$null = NULL;
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);
socket_bind($socket, '136.91.12.56', $port);
socket_listen($socket);
$clients = array($socket);

while (true) {
$changed = $clients;
socket_select($changed, $null, $null, 0, 10);
if (in_array($socket, $changed)) {
$socket_new = socket_accept($socket);
$clients[] = $socket_new;
$header = socket_read($socket_new, 52000);
perform_handshaking($header, $socket_new, $host, $port);
socket_getpeername($socket_new, $ip);
$found_socket = array_search($socket, $changed);
unset($changed[$found_socket]);
}

foreach ($changed as $changed_socket) {
while(socket_recv($changed_socket, $buf, 52000, 0) >= 1)
{
$received_text = unmask($buf);
$tst_msg = json_decode($received_text);
$type = $tst_msg->type;


break 2;
}
$buf = @socket_read($changed_socket, 1024, PHP_NORMAL_READ);
if ($buf === false) {
$found_socket = array_search($changed_socket, $clients);
socket_getpeername($changed_socket, $ip);
unset($clients[$found_socket]);
} }
}
}

socket_close($sock);

function send_message($msg)

foreach($clients as $changed_socket)

@socket_write($changed_socket,$msg,strlen($msg));
}
return true;
}
function unmask($text) {

Установил сертификат:
server{
listen 8443 ssl;
ssl_certificate /etc/ssl/sert.crt;
ssl_certificate_key /etc/ssl/sert.key;
server_name site.ru;
}

Теперь такая ошибка: WebSocket connection to 'wss://site.ru:8443/components/socket.php' failed: Error during WebSocket handshake: Unexpected response code: 404
