Real time map is not showing the data, it's just showing as Loading data. This issue is only with http link. With https link , we are able to view the data.
Location Provider:GeoIp Legacy(php)
Are you able to see any errors in the browser console?
I am attaching the errors and the screenshot. We have already set cors_domains = *
The Map should not need CORS headers as it is not a Cross-Origin-Request.
If this still occurs in the latest Matomo release, please reopen this issue or create a new one.
