The IP address of the visitors is not displayed

Hello friend,
After the some update in mid - year 2017, LiveHelperChat stopped showing IP of visitors. Displays only 127.0.0.1 for each visitor.
I think I have everything allowed everywhere.
Does anyone have any experience with this problem?

Thank you for every answer.

Re: The IP address of the visitors is not displayed

Well, not much I can do... Without having to login to server etc etc...

you can modify index.php and put under <?php

print_r($_SERVER);

And paste content there...

Re: The IP address of the visitors is not displayed

Hi Remdex,
I found something.
It worked last on PHP 5.6.40.
It stopped working on PHP 7.0.33 web hosting after migration.
I tried a new installation of LiveHelperChat on PHP 7.0.33 but still the same result.
All visitors have IP: 127.0.0.1   

Is it possible to do something about it?
Is there a problem with the new PHP features?

Re: The IP address of the visitors is not displayed

Sorry, but I just can't reproduce. But what I see is incorrect values from your hosting...

[HTTP_X_FORWARDED_FOR] = Should be real IP now it's 127.0.0.1
[REMOTE_ADDR] = 109.80.146.135 Real IP

And as of HTTP_X_FORWARDED_FOR always has higher priority. Please FIX your server configuration or tell your hosting that real IP should be in HTTP_X_FORWARDED_FOR this field...

Re: The IP address of the visitors is not displayed

Hi Remdex,
unfortunately, the situation cannot be solved.
Web hosting has a new security.
Is it possible to bypass this security in the next LiveHelperChat update?

I am sending you his statement.
Citation of technicial support:
************************************************************************
Good day,

this is due to the predominance of Nginx over Apache, this change occurred to maintain the stability of shared web hosts. Overriding x-forwarded-for with mod_remote_ip is automatically overridden to REMOTE_ADDR. This is a feature of shared hosting and I can't help you.

Thank you
Webmaster

Re: The IP address of the visitors is not displayed

Hi,

That's incorrect workflow they are doing.

You can modify this function and just after "public static function getIP(){"

return $_SERVER["REMOTE_ADDR"];

Re: The IP address of the visitors is not displayed

Hi Remdex,
thank you for support. I replaced the getIP function. I found this alternative  solution. It may be incorrect, but it works:

                      // Original to /*  */

    /* public static function getIP(){
        if (self::$couldflareRun == false){
            self::cloudflareInit();
            self::$couldflareRun = true;
        }
       if ( isset($_SERVER['HTTP_X_FORWARDED_FOR']) && $_SERVER['HTTP_X_FORWARDED_FOR'] != '' ) {
            $_SERVER['REMOTE_ADDR'] = str_replace(' ', '', $_SERVER['HTTP_X_FORWARDED_FOR']);   
            $parts = explode(',', $_SERVER['REMOTE_ADDR']);
            $_SERVER['REMOTE_ADDR'] = $parts[0];
        }
        $_SERVER['REMOTE_ADDR'] = isset($_SERVER['REMOTE_ADDR']) ? strip_tags($_SERVER['REMOTE_ADDR']) : '127.0.0.1';
        return $_SERVER["REMOTE_ADDR"];
    } */

   

// Modification   - show real IP

    public static function getIp(): string
{
    $ip = null;
    if (isset($_SERVER['REMOTE_ADDR'])) {
        $ip = filter_var($_SERVER['REMOTE_ADDR'], FILTER_VALIDATE_IP, FILTER_FLAG_IPV4);
    }
    return is_string($ip) ? $ip : '127.0.0.1';
}
