In case, accidentally deleted a certificate, here how to fix.
sudo certbot certonly --standalone -d deletedDomainname.comSince still nginx.conf contain information about the deleted certificate, it need reissue certificate ONLY = certonly flag to avoide nginx error such as:
nginx: [emerg] cannot load certificate "/etc/letsencrypt/live/domainname.com/fullchain.pem": BIO_new_file() failed (SSL: error:80000002:system library::No such file or directory:calling fopen(/etc/letsencrypt/live/domainname.com/fullchain.pem, r) error:10000080:BIO routines::no such file)
