Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:

Cleaning up challenges
Failed to renew certificate blog.elkhart.k12.in.us with error: Some challenges have failed.
My web server is (include version):
Server version: Apache/2.4.6 (CentOS)
Server built: Jan 25 2022 14:08:43
The operating system my web server runs on is (include version):
CentOS 7.9.2009
My hosting provider, if applicable, is: N/A
I can login to a root shell on my machine (yes or no, or I don't know): Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): No
The version of my client is (e.g. output of certbot --version
or certbot-auto --version
if you're using Certbot):
certbot 1.26.0
My webserver is up and running with several VirtualHost
configs, so I'm not sure where the 503 error is coming from. I've also confirmed:
- The firewall has ports 80 and 443 open for external traffic.
- The test file inside
.well-known/acme-challenge
is accessible at curl -I -m10 http://blog.elkhart.k12.in.us/.well-known/acme-challenge/testfile -
.well-known/acme-challenges
is accessible and writable byapache
in the web root directory.
Checking that file with curl
also works:
❯ curl -I -m10 http://blog.elkhart.k12.in.us/.well-known/acme-challenge/testfile
HTTP/1.1 200 OK
