Actually, I just checked one of the other domains, and it does specify the webroot in the format recommended above. This is the configuration file for that one:
# renew_before_expiry = 30 days
version = 0.31.0
archive_dir = /etc/letsencrypt/archive/agogecombatives.com
cert = /etc/letsencrypt/live/agogecombatives.com/cert.pem
privkey = /etc/letsencrypt/live/agogecombatives.com/privkey.pem
chain = /etc/letsencrypt/live/agogecombatives.com/chain.pem
fullchain = /etc/letsencrypt/live/agogecombatives.com/fullchain.pem
# Options used in the renewal process
[renewalparams]
account = 90d6840904da248a9a7ae688d0ae3d4e
authenticator = webroot
webroot_path = /var/www/html,
server = https://acme-v02.api.letsencrypt.org/directory
[[webroot_map]]
agogecombatives.com = /var/www/html
But it’s still not renewing automatically, with same error message as before. Any ideas on how I can get those certificates to work with certbot renew?
