Let’s encrypt renew

When I renew my certificate by the following command with running nginx, and error occured.

./certbot-auto renew --dry-run

Problem binding to port 443: Could not bind to IPv4 or IPv6.. Skipping.


As the document says, adding –webroot and -w option solved the problem. 😀

./certbot-auto renew --dry-run --webroot -w /var/www/html
