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: feros.fza.hs-kempten.de
I ran this command: certbot certonly --debug --test-cert --webroot -w /var/www/feros/ -d feros.fza.hs-kempten.de
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log

My web server is (include version):
Server version: Apache/2.4.10 (Debian)
Server built: Nov 28 2015 14:05:48
The operating system my web server runs on is (include version):
PRETTY_NAME="Debian GNU/Linux 8 (jessie)"
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
Tailing the log of apache parallel to execute the above command to issue a certificate shows
126.96.36.199 - - [21/Nov/2017:14:41:04 +0100] "GET /.well-known/acme-challenge/_XJccXCJnkgUs824FGYZMYImXbaZUbh02v5NkF2dolA HTTP/1.1" 200 310 "-" "Mozilla/5.0 (compatible; Let's Encrypt validation server; +https://www.letsencrypt.org)"
Which IMHO cleary states that the Let’s encrpypt server is actually able to request and get the challenge. I’m completely out of ideas.
Furthermore I put a file
.well-known/acme-challenge which gets displayed when accessing in a browser through
Any help is appreciated,
thanks in advance
