Certificate won't install

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: pedosupport.de

I ran this command: sudo certbot --nginx -d www.pedosupport.de -d www.pedosupport.de

It produced this output:
Requesting a certificate for www.pedosupport.de

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Domain: www.pedosupport.de
Type: unauthorized
Detail: 2001:8d8:100f:f000::200: Invalid response from http://www.pedosupport.de/.well-known/acme-challenge/CaTmY_rZ75wplhOpqcQ5sBpzuYblrD4HtJg78bDveYE: 204

Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.

Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

My web server is (include version): nginx

The operating system my web server runs on is (include version): Ubunto 20.4

My hosting provider, if applicable, is: ionos

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 2.6.0

That should probably be -d pedosupport.de -d www.pedosupport.de

The 204 error means your nginx is not sending the correct response. Certbot --nginx plug-in should have your nginx returning a 200 OK with the correct value to prove your domain.

Often we see 404 Not Found when something is wrong so 204 is unusual. Do you have some sort of security setting that is doing the 204?

certbot --nginx

gets me:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
The requested nginx plugin does not appear to be installed

i used

apt install python3-certbot-nginx

now it says its installed but still fails

Then you may have multiple versions of certbot installed.
You should review to ensure only one version remains.
Please also post the entire nginx configuration:
nginx -T

Are you on the correct system?
Let's see:
curl -4 ifconfig.io
curl -6 ifconfig.io

There is only one vhost shown:

server {
        listen 80 default_server;
        listen [::]:80 default_server;
        root /var/www/html;
        index index.html index.htm index.nginx-debian.html;

                try_files $uri $uri/ =404;
        }
}

I don't see how that can handle the https requests:

should be the correct server i had it preinstalled from an image and just installed nginx on top of that

root@ubuntu:/etc/nginx/sites-enabled# curl -4 ifconfig.io
87.106.197.137
root@ubuntu:/etc/nginx/sites-enabled# curl -6 ifconfig.io
curl: (7) Couldn't connect to server

You are NOT on the correct system:

Name:      pedosupport.de
Addresses: 2001:8d8:100f:f000::200
           217.160.0.40

thats weird i dont know how to fix that, i only have this one server any suggestion?

Who controls the DNS for this domain?
Who controls the other server [at IP 217.160.0.40]?

3 Likes

i dont even know where 217.160.0.40 is from, i do control the DNS, my domain is at all-inkl.com and redirects to my server at ionos.de

If by redirect, you mean:

That is NOT redirection.
That is a site within a site [inside a frame].
And the one inside is being accessed via an IP [not a name].
And LE won't "follow" such.
If you are going to secure your server, you should change the IPv4 address in the DNS zone to: 87.106.197.137.
And you should remove the IPv6 address from your DNS zone.
Then, you can use certbot to obtain a cert and use it to secure your site [via its' real name - not within an IP frame].

And do the same for the "www" addresses.

I see your certs are working so very nice.

But, you should review your redirects for pedosupport.de. You redirect HTTP requests for that to HTTPS but then issue a 404 Not Found.

HTTPS requests to your www domain respond with a 200 OK (and http redirects to https)

I think you should make sure HTTPS to your root domain redirects to your www domain

curl -I http://pedosupport.de
HTTP/1.1 301 Moved Permanently
Server: nginx/1.18.0 (Ubuntu)

curl -I https://pedosupport.de
