No statistics or counted visits


I have a blog (Hugo self-hosted) on a Raspberry Pi and I installed Matomo on the same pi.

The installation and configuration of Matomo went well and I inserted the code provided just before the / head into my index.html and in an article of the blog too.

But I do not have any coupled visits (while I visit my blog and another person also visit).

The code inserted in the Head:

<link href="" rel="alternate" type="application/rss+xml" title="Arnauld" /> <!-- Matomo --> <script> var _paq = window._paq = window._paq || []; /* tracker methods like "setCustomDimension" should be called before "trackPageView" */ _paq.push(['trackPageView']); _paq.push(['enableLinkTracking']); (function() { var u="//"; _paq.push(['setTrackerUrl', u+'matomo.php']); _paq.push(['setSiteId', '1']); var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0]; g.async=true; g.src=u+'matomo.js'; s.parentNode.insertBefore(g,s); })(); </script> <noscript><p><img src="//;rec=1" style="border:0;" alt="" /></p></noscript> <!-- End Matomo Code --> <script type="text/javascript" src="[/ynh_portal.js](view-source:"></script><link type="text/css" rel="stylesheet" href="[/ynh_overlay.css](view-source:"><script type="text/javascript" src="[/ynhtheme/custom_portal.js](view-source:"></script><link type="text/css" rel="stylesheet" href="[/ynhtheme/custom_overlay.css](view-source:"></head>

What can be the problem ?

Thank you for any suggestions.
