Hi @enjazvisa.com, now we can see your domain will get renewed on 2019/06/05 (5th of June, 2019) , meaning there is still a lot of time pending before it needs to get renewed.
Therefore, when you run the command, Lego detects it is still valid and there's still time left, so it does not renew the certificate.
Unfortunately lego does not have a
--force-renewal parameter yet, so until you are 30 days close to the expiration (or the value you set for
--days). Once renewed, it will be valid for three more months (90 days), and Let's Encrypt recommends renewing it each 60 days.
Let us know if you have any question.
