Document how to troubleshoot when the Matomo instance is showing a warning Chrome due to being added to safe browsing list (or other reasons)

trying to open my website, where Matomo code installed and here is what it shows:

after deleting Matomo code, everything works okay.

This issue has been mentioned on Matomo forums. There might be relevant details there:

This is more likely caused by bad IP address reputation (checked with https://scamalytics.com). The reported instances both have scam / fraud scores > 70

This looks a lot like your Matomo domain is on the google safe browsing list.
You can check here:

And report an incorrectly blocked site here:

@sandrocantagallo Did someone from Google tell you that you need to remove the tracking to be removed from safe browsing list, or is that an assumption from yourself?

Is maybe the domain of the matomo instance on the safe browsing list, causing all sites using that instance to land on the list as well?

I'm unfortunately not deep enough into that topic to provide a solution. Also I doubt there is much we can do in the code to solve that issue. Maybe someone else has an idea here...

Just installed Matomo on a sub domain of my plex....same issue as yours. I had inactivated the sub domain and deactivated the plugin WP matomo....only by this way the red flag is removed by Google.
So it is really due to the script loading matomo.js which is sensitive for Google :(

Finally how can you enable matomo ??? I don't understand if it feasible to use it if google is blocking automatically....

Here I think we would want to create a FAQ to explain how to troubleshoot this use case: imagine your Matomo instance has this problem suddenly, then you expect Matomo to have an FAQ to clearly explain why, the next steps on what to do.

Re-opening and renaming issue to restrict scope.
