I am creating a certificate like this
certbot certonly --webroot -w /var/www/certbot \
--email support@example.com \
--expand \
-d domain1.com,domain2.com,domain3.com \
--rsa-key-size 4096 \
--agree-tos \
--no-eff-email
However, subsequent certbot renew
runs do not renew this multi domain certificate it seems?
