> Mark kicked the cert update process and the issue should be fixed. For what it is worth, I wrote a small system based around a MySQL database, with a cron that downloads new certificates for all my servers when they are about to expire and save them in the database.
And different crons on the different servers that read the certificates from the databse, install them and do what it needs to do to activate them (restart the service, etc.) I have it working for Apache, postfix, courier-imap, freeradius, openldap, VMware ESXi... It is based around DNS challenge in Let's Encrypt. As it is crons, there is no daemon to reboot :) Best regards, Olivier
