@fknoll, you are welcome 
I forgot to say that it is a good idea to create a cron job so your certs can be renewed automatically. I propose this solution:
As root, create an cron job:
cronjob -e
And add this line at the end of the file:
41 */12 * * * /usr/local/sbin/certbot-auto renew --quiet --deploy-hook 'echo "\nI have renewed the cert located on ${RENEWED_LINEAGE} and this cert contains the following domains ${RENEWED_DOMAINS}\n\n" >&2' --post-hook "systemctl reload nginx"
And save the file.
With above cron job entry:
1.- certbot-auto will run twice a day (12:41 and 00:41).
2.- Variable ${RENEWED_LINEAGE} will point to the config live subdirectory containing the new certs and keys.
3.- Variable ${RENEWED_DOMAINS} will contain a space-delimited list of renewed cert domains.
4.- You can use --post-hook to reload/restart your services, in this example I’m reloading nginx so change it to fit your needs.
As I said, it will run twice a day but first, it will check whether any of your certs expire in less than 30 days, if the answer is no, it does nothing, if any of your certs will expire in less than 30 days, it will renew your certs, will send a mail with the domains renewed and will reload nginx.
If you want to specify a mail address to be informed then remember to add a MAILTO variable to the cronjob at the top of file, for example:
crontab -e
MAILTO="user@domain.tld"
41 */12 * * * /usr/local/sbin/certbot-auto renew --quiet --deploy-hook 'echo "\nI have renewed the cert located on ${RENEWED_LINEAGE} and this cert contains the following domains ${RENEWED_DOMAINS}\n\n" >&2' --post-hook "systemctl reload nginx"
If you don’t specify a MAILTO variable it will send the mail to root@machine_hostname
The mail that you will receive will have this look:
Error output from None:
I have renewed the cert located on /etc/letsencrypt/live/yourdomain.tld and this cert contains the following domains yourdomain.tld example1.yourdomain.tld example2.yourdomain.tld otherdomain.tld
Hope this helps.
Cheers,
