I have a few websites, and everything was running perfectly for the past months, but all of a sudden, they don't work anymore on Chrome for computers with Windows 7.
It works fine on Mozilla for these computers, and on all browsers with Windows version higher than 7.
Up at this point I've tried different solutions found online in articles like this: https://kinsta.com/knowledgebase/net-err_cert_date_invalid/
But nothing seems to work. On these computers, there are websites (other than mine) that have the same issue. The only common thing between these computers is the Windows version and the browser used.
If it helps, here is one of the websites https://suplimentenaturiste.ro/
I am thinking there must be an issue with the SSL itself, that was generated using Let's Encrypt.
