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. https://crt.sh/?q=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: lecarnetblanc.com
I ran this command: sudo certbot --apache -d lecarnetblanc.com
It produced this output:

Hi @diltech
you have two ip-addresses - ipv4 and ipv6.
But the answers are different: Let's Debug
[Address Type=IPv4,Server=Apache/2.4.6 (CentOS) OpenSSL/1.0.2k-fips mod_fcgid/2.3.9 PHP/5.4.16,HTTP Status=404] vs [Address Type=IPv6,Server=,HTTP Status=302,Number of Redirects=2,Final HTTP Status=200]
Perhaps the ipv6 address points to another server or configuration.
Are http://184.144.176.224/ and http://2602:ff23:0:8888::207/ the same server?
One solution: Remove the ipv6 - address. Create the certificate and install it. Then you have 90 days to fix the error.
good, i remove my ipv6 address and now all work. Thanks
