Certbot usage for renewing Jot-Server certification automatically

Hi folks,

since MSolutions seems to have quit his participation here on UNA.io and his Jot-Server service without any prior announcement, I'm forced to setup my own Jot-Server, again.

Now my question to all of you who have done that on their own, did you manage to auto-renew certificates using certbot with free letsencrypt certificates and cron?

Any help or experience would be highly appreciated.
