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:
I ran this command:
certbot renew --dry-run
It produced this output:
The following certs could not be renewed:
/etc/letsencrypt/live/mail.increaseyourskills.com/fullchain.pem (failure)
** DRY RUN: simulating ācertbot renewā close to cert expiry
** (The test certificates above have not been saved.)
1 renew failure(s), 0 parse failure(s)
IMPORTANT NOTES:
-
The following errors were reported by the server:
Domain: mail.increaseyourskills.com
Type: unauthorized
Detail: Invalid response from
http://mail.increaseyourskills.com/.well-known/acme-challenge/l0cc2g1E7spZ9WnAJrdmCGidjtdhMb7EQ_S3MzLw0cE:
ā\r\n404 Not Found\r\n<body
bgcolor=āwhiteā>\r\n404 Not
\r\n
Found
āTo fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
My web server is (include version):
nginx 1.14
The operating system my web server runs on is (include version):
Ubuntu 18.04.1 LTS (bionic)
My hosting provider, if applicable, is:
Hetzner (https://www.hetzner.de/)
I can login to a root shell on my machine (yes or no, or I donāt know):
Yes.
Iām 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 youāre using Certbot):
certbot 0.28.0
My additional thoughts:
I read through some similar souding threads and already tested a little bit of some advice.
For instance I created a file in the webroot under ./well-known/acme-challenge. I could access this file without any issues.
I also made sure to have the right file and group permissions on this folder.

This domain is the only one which is not compatible for the renewing process for an unknown reason (the other domains are working like a charm)
I would appreciate your help.
