Image tracking no visitors

I am not getting any results testing for a new website. I’m not using JavaScript just image tracking. The URL showing in the website logs is

GET /analytics/matomo.php?idsite=4&rec=1&action_name=Media%20Manager HTTP/1.1

This is returning 200 to the browser.

However the dashboard is not showing any visitors and log is empty ?
Version 3.13

Odd but changed the url to piwik.php and now working.
