Matomo configuration

[DeMiro5001]

I have installed matomo and lychee on the same server.
Server yunohost 12.0.9.1
Matomo 5.1.2
Lychee 6.2.0

I followed the documentation to setup matomo with lychee, but I don't get any analytics (2 or 3 days). I tested in matomo (test installation button) and got Tracking code verification failed. Please verify that you have installed the code correctly. Matomo has also proposed to 'Install Matomo with Vue.js (recommended for you)' following this guide, which I didn't test before I get your advice.

What I have done so far :

• Edit .env and set SECURITY_HEADER_SCRIPT_SRC_ALLOW and SECURITY_HEADER_CSP_CONNECT_SRC
• Run php artisan config:clear (don't know if it's necessary)
• Added the code snipet of matomo in lychee > settings > advanced settings > change js

What am I doing wrong?
Thanks for your help
