Debug when 0 hits

Hello,

we are successful run matomo since a year with 9 sites. Few days ago I added a new site, with the same settings of the other sites we have, but it does not receive hits.

Looking at matomo access.log I can see:

X.X.X.X - - [20/Jan/2023:09:14:23 +0100] "GET /matomo.js HTTP/2.0" 200 66116 "https://www.oursite.com/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36" "-"

So the access.log hits related to the ‘not working’ website looks to be the same we can see for the working websites.

How to debug why I can’t see them in matomo?
We do not have space problem of course.
