My domain is: blog.elkhart.k12.in.us
I ran this command:
certbot renew -v --dry-run
It produced this output:

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):
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):
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-challengeis accessible at curl -I -m10 http://blog.elkhart.k12.in.us/.well-known/acme-challenge/testfile
.well-known/acme-challengesis accessible and writable by
apachein 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 Date: Fri, 15 Apr 2022 18:12:38 GMT Server: Apache/2.4.6 (CentOS) OpenSSL/1.0.2k-fips Phusion_Passenger/6.0.4 mod_wsgi/3.4 Python/2.7.5 PHP/7.3.33 Last-Modified: Fri, 15 Apr 2022 17:58:33 GMT ETag: "0-5dcb528ad70b0" Accept-Ranges: bytes Content-Type: text/plain; charset=UTF-8
I'm at a loss for what to do at this point. Any tips on where to look next?
