Could you please post the output of the following commands?
ls /etc/letsencrypt/archive
ls -l /etc/letsencrypt/live/zenit4you.win
ls -lt /etc/letsencrypt/archive/zenit4you.win
certbot-auto certificates
I’m thinking that this sounds similar to a problem seen recently where the new certificate is issued correctly, but for some unknown reason the symbolic links in /etc/letsencrypt/live don’t get updated, or get updated incorrectly.
Are you using Docker?
