Hey @fbsena, you can run crontab -e
and find the cron job that looks something like this 36 0 * * * "/etc/letsencrypt"/acme.sh --cron --home "/etc/letsencrypt" --config-home "/etc/letsencrypt/config" > /dev/null
You can run "/etc/letsencrypt"/acme.sh --cron --home "/etc/letsencrypt" --config-home "/etc/letsencrypt/config"
from your SSH prompt and see the output to know that it's working.
I created a couple of other scripts to check the expiration dates and to switch from certbot to acme.sh but I am not sure you'll need those.
