I used tutorial --> https://www.howtoforge.com/tutorial/server-monitoring-with-munin-and-monit-on-ubuntu-16-04-lts/2/. Monit used domain name of the server with green padlock (lets encrypt cert for fqdn and ISP panel). I also configured it to work with ISPconfig. Currently When I try enter on s1.example.com:2812 I have information that website cert expired "1 Feb 2018, 07:27" and website uses hsts and this bring to unable add exception. Now I can enter monit site only using ip address with port. I tried add in monitrc config file cert from /etc/letsencrypt/live/s1.example.com but after restart monit service I have error that cert has 644 but it can max has 700 privileges. How to renew this cert?
