Hello

I wonder if someone could provide me with the best practice or built in methods, for renewing certificates used in FusionBPX?

I generated the original certificate using the script located here: /usr/src/fusionpbx-install.sh/debian/resources/letsencrypt.sh, which worked perfectly and generated the certificate.

I have seen on numerous posts on here people saying that it should have created a cron for dehydrate to renew however having read through the script myself i don't believe it ever would have.

The certificate is for a standard singular domain not a wildcard.

Kind regards,

Thomas Burridge

I'm fairly certain you can just re-run the renewal command in a cronjob, I guess every day.

/usr/local/sbin/dehydrated --cron --config /etc/dehydrated/config
