For anyone using apache mod_md.
Simply add/change the minimum date. By default I believe its 10% or 30 days. Honestly I can't remember.
MDRenewWindow 21d
For me I simply changed 21 to 60 and restarted the apache service. I got a new certificate within a minute or two automatically.
Your apache installation will possibly be different as I run my server on FreeBSD I added the setting to:
/usr/local/etc/apache/httpd.conf
If you have issues with mod_md change your error logging to something higher like debug and look into your log file for issues regarding mod_md.
Loglevel debug
The following is where the log file is placed by default, but you can change this in the apache config file.
/var/log/httpd-error.log
Again this is for FreeBSD installs so locations of files and names might be different.
Hopefully someone finds this useful.
