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: office.hb-os.de
I ran this command: certbot renew --dry-run
It produced this output:Attempting to renew cert (office.hb-os.de) from /etc/letsencrypt/renewal/office.hb-os.de.conf produced an unexpected error: Failed authorization procedure. office.hb-os.de (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://office.hb-os.de/.well-known/acme-challenge/YhFfcxB9HzhNLAl79MF2_MWdrw92LiuEPEH4gthlXuw
My web server is (include version): Apache2
The operating system my web server runs on is (include version): Debian 9
My hosting provider, if applicable, is:
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): 0.28.0
I accidently deleted before the .well-known folder, so I made it again with 777 right. I also made acme-challenge below. Both is reachable from outside. The problem itself is that certbot does not generate the files. I checked the webroot in conf-file and it has the right setting. Does anybody has an idea why the files are not generated?
