Hi @virgilio27,
A 403 HTTP status response means “Forbidden Request”, meaning something is blocking access to the REST API on your website (see: Is WordPress Popular Posts compatible with security / firewall plugins?)
Make sure to allow WPP access to the REST API so it can do its job.
is there any way to check the connection to the REST API? I have access to the server logs
Try visiting that URL using a web browser while being logged out from the admin dashboard (or use Incognito mode).
Yes, it view very much text, like source code
If you’re able to view it then access to the REST API is not being blocked, the problem is likely something else.
If you’re using a caching plugin then please read this FAQ as chances are that’s what’s causing the issue: Is WordPress Popular Posts compatible with caching plugins? (Pay special attention to the second bullet.)
I use rocket cache and clear cache every 8 hours, may I have to exclude some route?
No, that should be fine. If that’s the case then I have no idea what’s going on. You’ll need to do some more debugging (or get a developer to do that for you) in order to figure out what’s causing these 403 Forbidden error messages.
Marking as resolved due to inactivity.
