严重性：警告 - > fsockopen（）：无法连接到212.71.135.20:11300

I am trying to connect to my pheanstalk in my application with the code below

public function fsockopen($hostname, $port = -1, &$errno = null, &$errstr = null, $timeout = null)
{
    // Warnings (e.g. connection refused) suppressed;
    // return value, $errno and $errstr should be checked instead.
    return @fsockopen($hostname, $port, $errno, $errstr, $timeout);
}

But i get the error below in my log file

Severity: Warning --> fsockopen(): unable to connect to 212.71.235.57:11300 (Connection refused) /home/path/to/my/application/libraries/pheanstalk/classes/Pheanstalk/Socket/StreamFunctions.php 71

I tried to telnet 212.71.135.20 11300 and it works fine by repsonding Connected to domain.com Escape character is '^]'.

Is there anything i have to try to do again to make this work please ?

PS: I tried to use socket_connect & socket_create but none still works.
