Same ip on different visits

Hello,
I installed piwik on our centos server, but all visits show the same ip even though they come from different sources. See screenshot
Can you please help?
Thank you

Hi there, see this FAQ: How do I configure Piwik when the server is installed behind a proxy? - Analytics Platform - Matomo

Hi Matt,
thank you for your reply. I’ve already tried the faq you suggested, of course, but it doesn’t work. Could you suggest some other workaround?

Are you using the PHP-based PiwikTracker? A bad auth_token will cause the server’s IP to be reported rather than the client.

No, I’m using the script provided by piwik after inserting a new website.

create a file info.php with content <?php phpinfo();
then look in output and where do you see your real IP address?
