Multi-domain certificate will not renew on certbot renew

Help
1

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?

Hi and welcome!

What is the error message shown in the logs?
Are all three domains served from the same webroot?
