I can manually open the acme-challenge link (in the short time it is available), via the web site. This is the first of 4 servers that I use certbot with the others are not yet due for renewal.
My domain is:
mail.vd-hoven.nl
I ran this command:
certbot certonly --dry-run -v --webroot -w /var/www/html -d mail.vd-hoven.nl
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator webroot, Installer None
An RSA certificate named mail.vd-hoven.nl already exists. Do you want to update
its key type to ECDSA?
(U)pdate key type/(K)eep existing key type: u
Simulating renewal of an existing certificate for mail.vd-hoven.nl
Performing the following challenges:
http-01 challenge for mail.vd-hoven.nl
Using the webroot path /var/www/html for all unmatched domains.
Waiting for verification...
Challenge failed for domain mail.vd-hoven.nl
http-01 challenge for mail.vd-hoven.nl
Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:
Domain: mail.vd-hoven.nl
Type: connection
Detail: 83.247.98.143: Fetching http://mail.vd-hoven.nl/.well-known/acme-challenge/5KINyeL46hg7vXdVbDeOT83THeBOrOySip_T4OPtfBg: Timeout during connect (likely firewall problem)
Hint: The Certificate Authority failed to download the temporary challenge files created by Certbot. Ensure that the listed domains serve their content from the provided --webroot-path/-w and that files created there can be downloaded from the internet.
Cleaning up challenges
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.
