Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
---.removed.---
I ran this command:
certbot renew --dry-run
It produced this output:
AH00526: Syntax error on line 5 of /etc/httpd/conf.d/ssl.conf:
Cannot define multiple Listeners on the same IP:port
My web server is (include version):
Apache/2.4.37 (centos)
The operating system my web server runs on is (include version):
CentOS Linux 8 (Core)
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 1.18.0
When trying to get new certificates or renew old ones, I get the error:
AH00526: Syntax error on line 5 of /etc/httpd/conf.d/ssl.conf:
Cannot define multiple Listeners on the same IP:port
There have been a few references to the same error and the solutions have been to comment out "Listen 443" on one config file or another. In my case, that line is in:
grep -i -r "Listen 443" /etc/
/etc/httpd/conf.d/ssl.conf:Listen 443 https
/etc/httpd/conf/httpd.conf:Listen 443
If I comment out either one, the site fails to load and the certbot error changes to:
Failed to renew certificate ---.removed.--- with error: Some challenges have failed.
