Failed authorization procedure

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:
wed.dyndns.org
I ran this command:
letsencrypt
It produced this output:
root@linuxserver:~# letsencrypt

i have configured the ServerName option in /etcapache2/sites-enabled/000-default.conf and …/000-default-le-ssl.conf to ServerName “wed.dyndns.org”. But after reloading the new configuration there is no change of the error.

Maybe the problem with the "/.well-known/acme-challenge… configuration ??

There is no folder under /var/www/html named “/.well-known …”.

I have also a “/.well-known/”-Problem with my nextcloud configuration. It 's configured via “.htaccess” by a nextcloud file, but also announced as warning.

The apache module rewrite is activated.
The letsencrypt / certbot error describes also that “http://wed.dyndns.org/.well-known/acme-challenge/YtemJnQ3mkapBIC3mR3NIUzGq4oDWChkTbaOZydxMoY [62.54.176.98]” is not found 404.

The renewal was successful from 2016 until 16th decembre 2019 without any problems.

In the forum I found solutions for the “/.well-known/…”-problem only for the nginx-server, not for apache2.

What are the important settings in apache2 to prevent this /.well-known/acme-challenge/… problem ?
What was the change in letsencrypt-system after decembre 2019 ?

“check-your-website” output:

    A	Good: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

I`m not able to eliminate the renewal error.

Is it possible to remove the letsencrypt-system completely from my server for installing it completely new ? Will that procedure effect in an right configuration ?

You need to use the </> button in the editor if you want me to be able to understand that stuff. (select, then click)

JuergenAuer · March 23, 2020, 11:24am

Hi @kaiww

your apachectl -S shows the solution.

There is no vHost with that domain name.

Add one.

kaiww · March 23, 2020, 11:36am

Thank You for Your help. The mistake was completely different, sorry.

In my router, there was port-forwarding for http: (80) and https: (443) to different ip-addresses.

I changed the http-forwarding to the same host as https, and now there is no more error.

I 'm sorry for producing such confusion.
