SSL issue to www

Without “www” the site is safe while when there is “www” it is unsafe, why?
Ex.
Prupix – Studio grafico Online (safe)
https://www.prupix.it/martina/ (unsafe)
Thanks for any replies

please copy the complete command from the cyberpanel main logs and paste it at the terminal then show me output

The problem seems to have settled on its own.
Thanks for the support
