Renew domain keeps failing with 404 errors

daviddeleeuw · November 11, 2021, 7:38am

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:
dukium.org
I ran this command:
certbot renew --dry-run --apache
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log

IMPORTANT NOTES:

The following errors were reported by the server:

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.

My web server is (include version):
Server version: Apache/2.4.18 (Ubuntu)
Server built: 2020-08-12T21:35:50

The operating system my web server runs on is (include version):
Linux dukium.org 4.4.0-1160.41.1.vz7.183.5 #1 SMP Thu Sep 23 18:26:47 MSK 2021 x86_64 x86_64 x86_64 GNU/Linux
My hosting provider, if applicable, is:
interserver.net
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 0.31.0

The run fails on:
http://dukium.org/.well-known/acme-challenge/i3qzFLTdN0d2BrupRrh_Y7VqaFconV6lrD9WGR66bkI

But
http://dukium.org/.well-known/acme-challenge/a
works !

There is a redirection in place from /var/www to /usr/local/mgr5 for the whole website

There is a "letsencrypt.conf"
Alias /.well-known/acme-challenge/ /usr/local/mgr5/www/letsencrypt/
<Directory "/usr/local/mgr5/www/letsencrypt/">
Order allow,deny
Allow from all
= 2.4>
AllowOverride None
Require all granted

The system ran years ago on another provider with cpanel, was moved. The certificate was provided through cloudflare. The certificate present on the system is from 2017. I was not involved in this this yesterday, so can not really follow the history.
Did not work with certbot before.
Thanks for your help.

Hi @daviddeleeuw and welcome to the LE community forum

How does that "work"?

Please start by showing the output of:

Two issues obviously (?)
1.redirection to https
2. certificate goes to www.dukium.org instead of dukium.org
Not sure if this points to the issue
David

rg305 · November 11, 2021, 9:38am

There is a name:port overlap/conflict caused because this file is being included into your running config:

daviddeleeuw · November 11, 2021, 10:37am

RG305
Now it is OK ?

apachectl -t -D DUMP_VHOSTS
VirtualHost configuration:
66.23.235.247:80 dukium.org (/etc/apache2/vhosts/www-root/dukium.org:1)

Still same problem.

Going forward or backward ?

daviddeleeuw · November 11, 2021, 11:17am

There is a redirection from http://dukium.org to https://www.dukium.org . Performed by Wordpress. Should probably stop this redirect for letsencrypt. Where ?

rg305 · November 11, 2021, 11:18am

Definitely forward

Edit that file and change both lines:

To:
*:80
*:443

rg305 · November 11, 2021, 11:19am

Thats only a problem if the two vhosts have different DocumentRoots.

I notice there is no redirect exclusion for letsencrypt here. Is that the problem ?

Let me check that.
Yeah, the WordPress is redirecting to HTTPS.
Please show the 443 section.

Should these ssl lines be there ? Seem to point to other places ?

rg305 · November 11, 2021, 11:47am

Ok. Let's try it this way:

certbot --dry-run --apache \
--webroot -w /var/www/www-root/data/www/dukium.org \
-d "dukium.org,www.dukium.org"

Which may fail with the same error...
If so, then try:

certbot --dry-run certonly \
--webroot -w /var/www/www-root/data/www/dukium.org \
-d "dukium.org,www.dukium.org"

daviddeleeuw · November 11, 2021, 11:51am

Currently, the renew verb is capable of either renewing all installed certificates that are due to be renewed or renewing a single certificate specified by its name. If you would like to renew specific certificates by their domains, use the certonly command instead. The renew verb may provide other options for selecting certificates to renew in the future.
