what happened is that , one time
before I tried renew my cert with
sudo ./letsencrypt-auto --renew-by-default certonly --standalone --email jordy@yaroslab.com -d heidelberg.yaroscloud.com
(and you said --renew-by is the same that forcce renewal that use this is wrong and I will never use it again 
and never be used in automatik task)
so I should use
I remember when I try created my certificate again and I revoke my certificate with
sudo ./letsencrypt-auto revoke -d heidelberg.yaroscloud.com --cert-path /etc/letsencrypt/live/heidelberg.yaroscloud.com/cert.pem
also I used
sudo ./letsencrypt-auto certonly --server https://acme-staging.api.letsencrypt.org/directory
and then create cert I suposse like this create heidelberg.yaroscloud.com-0001 , beacause I couldn’t before.
I think that in that way I lost the previous certificate and then the other one was created (0001)
