404 from .well-known/challenge


#1

Hi,
awsdevopro and Juergen - sorry for intrusion. looks like I have same problem. and I am not sure I understand why is that.

My domain is:
stored2ship.com
I ran this command:
certbot --version
certbot 0.29.1
#sh -c “sed -i.bak -e ‘s/^(pref_challs.)tls-sni-01(.)/\1http-01\2/g’ /etc/letsencrypt/renewal/; rm -f /etc/letsencrypt/renewal/.bak”

certbot renew --dry-run

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log

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):

Well-known/acme-challenge/test gives 404

404 error is good in that http can reach your server.

Now we just need to figure out why the /.well-known/acme-challenge/ requests don’t reach the files created for them.

Please show all the vhost config files for “stored2ship.com”.
grep -Eri 'servername|serveralias' /etc/apache2 | grep stored2ship.com


#3

Hi @stored2ship

your main configuration is ok ( https://check-your-website.server-daten.de/?q=stored2ship.com ):

Redirects http -> https, both of your /.well-known/acme-challenge redirects to https + www, there is the expected status 404.

So try to find your DocumentRoot (in your vHost), then use it:

certbot run -a webroot --dry-run -w yourDocumentRoot -d stored2ship.com -d www.stored2ship.com

#4

The redirection to WWW also inserted “index.php” - that will break almost everything being redirected.


#5

Oh, sorry, not seen - thanks.

@stored2ship - this is bad.


#6

Hi Rudy,

could it be because script assumes the directory is /etc/apache2? it’s just my guess.

grep -Eri ‘servername|serveralias’ /etc/httpd | grep stored2ship.com
/etc/httpd/conf/httpd.conf:#ServerName www.stored2ship.com:80
/etc/httpd/conf/httpd.conf:ServerName stored2ship.com
/etc/httpd/conf/httpd.conf: ServerName stored2ship.com
/etc/httpd/conf.d/ssl.conf:#ServerName stored2ship.com:443
/etc/httpd/conf.d/ssl.conf:ServerName www.stored2ship.com:443

[sm@stored2ship ~]$ httpd -v

Hi Juergen,

grep DocumentRoot conf/httpd.conf
DocumentRoot “/var/www/html”
DocumentRoot “/var/www/html”
#DocumentRoot “/var/www/html”
[root@stored2ship httpd]# certbot run -a webroot --dry-run -w /var/www/html -d stored2ship.com -d www.stored2ship.com
–dry-run currently only works with the ‘certonly’ or ‘renew’ subcommands (‘run’)

-The redirection to WWW also inserted “index.php” - that will break almost everything being redirected.

What do you mean? Is it incorrect? Or were you talking about certbot script?


#9

Try:

certbot renew --webroot -w /var/www/html -d stored2ship.com -d www.stored2ship.com --dry-run

Yes, very incorrect.
Please show the redirection statement used (or the complete port 80 & port 443 vhost config files).


#10

Yes, this is very incorrect and the first thing you should fix.


#11

cat httpd.conf
#Include /etc/httpd/conf.d/ssl.conf
#Include /etc/httpd/conf.d/php.conf
ServerRoot “/etc/httpd”
#Listen 104.251.218.64:80 http
#Listen 104.251.218.64:443 https
#Listen 443
Listen 80

Example:

LoadModule foo_module modules/mod_foo.so


#12

ok. Thank you Juergen.

I removed index.php from redirection and ran:

certbot renew --webroot -w /var/www/html -d stored2ship.com -d www.stored2ship.com --dry-run
Saving debug log to /var/log/letsencrypt/letsencrypt.log
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.

Is that correct response from certbot?


#13

renew renews, --dry-run tests the renew. So you can’t use both subcommands in one command.

Your certificate is new, so use --dry-run.


#14

After this correction to httpd.conf I was trying to run certbot renew --dry-run:

it looks like script is dying at the very beginning in _init:frowning:

The command line called for webroot…
Why not chose option #3?
