Can't update certificate, get weird error

Help
1

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: weilichskann.servebeer.com

I ran this command: certbot -v renew

It produced this output: dpaste/URKq (Bash)

My web server is (include version): Apache/2.4.38 (Raspbian)

The operating system my web server runs on is (include version):

OS: Raspbian 10 buster
Kernel: armv7l Linux 5.10.60-v7+
Uptime: 1d 15h 16m
Packages: 753
Shell: 10941
CPU: ARMv7 rev 4 (v7l) @ 4x 1.2GHz [56.9°C]
GPU: BCM2708
RAM: 433MiB / 966MiB

My hosting provider, if applicable, is: hosted at home

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

Hi @Bratzmeister, welcome to the LE community forum :slight_smile:

It seems that when you last obtained this cert it was via --standalone authentication.
And today there is a running service using the HTTP port.
Likely:

You can either:

  • stop apache before running certbot in --standalone mode (not recommended)
  • use the --apache authenticator (not my first choice)
  • use Apache for web service and use certbot in --webroot mode (my first choice)

If you should need any help with implementing any of those choices, just ask.

3

Please elaborate why you prefer the webroot over the apache plugin, as for many (novice) users, the apache plugin is probably the most easy method, if the Apache configuration is compatible of course.

Because Apache is notorious for running at all cost.
There is a much higher probability of success with the webroot authenticator than with the apache.
I can't think of one example where apache would work and webroot would fail.
Whereas this community is filled with counter examples.

5

i tried webroot but i guess i'm missing some files that it wants me to put
--apache didnt work, maybe im missing a plugin
--standalone, yields exactly the same error as plain certbot renew

6

Maybe you didn't understand me.
certbot renew is doing certbot renew --standalone
Please review the file:

If you need help with implementing --webroot, just ask for it.

7

Likely a badly configured Apache.
You can start to unravel that, with:
sudo apachectl -t -D DUMP_VHOSTS

8

sudo apachectl -t -D DUMP_VHOSTS VirtualHost configuration: *:443 weilichskann.servebeer.com (/etc/apache2/sites-enabled/000-default-le-ssl.conf:2) *:80 weilichskann.servebeer.com (/etc/apache2/sites-enabled/000-default.conf:1)

9

Then there are no more than those two files to review.

Feel free to post them here if you need any help with them.

10

I'm obviously not Rudy, but I'd say because the apache plugin makes many assumptions about how your apache config files are laid out, which are often incorrect. OTOH, if you know where the web root location is, and your web server isn't configured to do something stupid like deny access to directories starting with a . , webroot is almost certain to work.

i rebooted the system and now i get this:

And what did you expect (for it to suddenly work - simply by rebooting it)?
That's not how things get fixed - well not unless you are running Windows - LOL

13

no, the error is a different one-.-

14

This error shown is because:

  • you are no longer trying to run certbot in standalone mode (which would conflict with apache for port 80)
  • your Apache config is incomprehensible to certbot and it fails to get the job done with the current Apache config.

Which is what I expected and why I pointed you in the direction of:

  • using webroot authentication
    OR
  • show the apache config files and maybe we can fix the mess apache has made

According to those files, the HTTP request from LE should be redirected to HTTPS.
But the error you showed in the post above last has only HTTP.
So, LE isn't being redirected; Thus not reaching your HTTP site.
We don't see enough of the logfile to understand exactly why the HTTP LE request has failed.
Likely "firewall problem".
Since I can't reach your site via HTTP (and thus don't get redirected) either:

curl -Iki weilichskann.servebeer.com
curl: (56) Recv failure: Connection reset by peer

Please show the LE log file (/var/log/letsencrypt/letsencrypt.log) and confirm that the entire Internet can reach your site via HTTP.

No reason not to try the Apache plugin to begin with IMO. It doesn't break anything, if it doesn't hurt, try it. Suggesting --apache is way more easy than suggesting --webroot and explain how and where to find the webroot path et cetera.

18

i obviously have port 80 and 443 forwarded to my machine.
