Hello.
On our roundcube installation I see the following error.
When I send message, roundcube hangs with status "Sending message" for
several minutes. Then I receive "Request time out". However, the message
is sent. It's related to spell checker. I see that after sending message
our roundcube host opens connection to spell.roundcube.net (443 port)
and they are talking for a second:


I've inserted several debug messages in rcube_spellcheck_googie.php
and now it looks like

    function check($text)
    {
        $this->content = $text;

        openlog("webmail",LOG_PID|LOG_ERR,LOG_DAEMON);
        $data=date("Y/m/d H:i:s");
        syslog(LOG_ERR," $data googie is starting check");

        // spell check uri is configured
        $url = rcube::get_instance()->config->get('spellcheck_uri');

        if ($url) {
            $a_uri = parse_url($url);

$ssl = ($a_uri['scheme'] == 'https' || $a_uri['scheme']== 'ssl');

            $port  = $a_uri['port'] ? $a_uri['port'] : ($ssl ? 443 : 80);
            $host  = ($ssl ? 'ssl://' : '') . $a_uri['host'];

$path = $a_uri['path'] . ($a_uri['query'] ?'?'.$a_uri['query'] : '') . $this->lang;

        }
        else {
            $host = self::GOOGIE_HOST;
            $port = self::GOOGIE_PORT;
            $path = '/tbproxy/spell?lang=' . $this->lang;
        }

        $path .= sprintf('&key=%06d', $_SESSION['user_id']);

        $gtext = '<?xml version="1.0" encoding="utf-8" ?>'

.'<spellrequest textalreadyclipped="0" ignoredups="0"ignoredigits="1" ignoreallcaps="1">'.'<text>' . htmlspecialchars($text, ENT_QUOTES,RCUBE_CHARSET) . '</text>'

            .'</spellrequest>';

        $store = '';
        if ($fp = fsockopen($host, $port, $errno, $errstr, 30)) {
            $data=date("Y/m/d H:i:s");
            syslog(LOG_ERR," $data googie connected");
            $out = "POST $path HTTP/1.0\r\n";
            $out .= "Host: " . str_replace('ssl://', '', $host) . "\r\n";

$out .= "User-Agent: Roundcube Webmail/" . RCMAIL_VERSION ." (Googiespell Wrapper)\r\n";

            $out .= "Content-Length: " . strlen($gtext) . "\r\n";
            $out .= "Content-Type: text/xml\r\n";
            $out .= "Connection: Close\r\n\r\n";
            $out .= $gtext;
            fwrite($fp, $out);

            $data=date("Y/m/d H:i:s");
            syslog(LOG_ERR," $data googie sent message");

            while (!feof($fp)) {
                $store .= fgets($fp, 128);
                $data=date("Y/m/d H:i:s");
                syslog(LOG_ERR," $data googie is reading");
            }
            fclose($fp);
            $data=date("Y/m/d H:i:s");

syslog(LOG_ERR," $data googie has closed connection. Wehave read $store");

        }



After this I've received the following:
