I have a iRedmail server. Few weeks ago I checked it everything worked fine. Today I tried to open RoudCube, SOGo, iRedAdmin and non of this web services was available. Everything had a problem with https certificate. I checked the cron for renewal certs and it is there. Here is the code

0 3 * 1-12 * certbot renew --post-hook '/usr/sbin/service postfix restart; /usr/sbin/service nginx restart; /usr/sbin/service dovecot restart'

I tough every day is not necessary if cert is valid for 90 days. Ones a month should be enough. Even though I have a renewal email message everyday in mailbox. It seems there is another cron to renew certs. As I remember new Certbot do it automatically at the background....

According this documentation I made restart of services and it is running. But why the crone from doc does not contain MySQL and OpenLDAP restart?

I would like to understand what happened. Thanks.
