Another issue had to do with a bug in plesk.
Check your Plesk Web Statistics at the bottom of the page:
The most frequent HTTP Status code is “301 – Moved permanently (redirect)” at https://domain.com/plesk-stat/webstat/. It takes 49.5%.
In addition, “Permanent SEO-safe 301 redirect from HTTP to HTTPS” is checked under Domains > domain.com > Hosting Settings > Security section.
In this way the SSL traffic is not shown under Domains > domain.com > Web Statistics.
This issue was caused by a product defect. A bug has been already created: PPPM-548: SSL traffic is not shown in webstat.
